Procedures for making such liquid phenol-formaldehyde condensation products are well known. The mechanism by which these improved properties are obtained is not understood. The dispersion is compatible with liquid phenol resole resins and readily intermixes to give a uniform blend of the copolymer with the phenolic resin. 1 match found for PHENOL-FORMALDEHYDE RESIN. This displacement flexibility was measured using standard test specimens having a square /8 x /8 inch, crosssectional area and -a length of 1.5 to 2 inches. Then standard test strips were cut from each cured sheet and used to measure the flex strength by standard methods. Phenolharze (PF-Harze, Phenol-Formaldehyd-Harze) sind Kunstharze (Kondensationsharze), die durch Polykondensation aus Phenolen und Aldehyden hergestellt werden.

Liste der der PIC-Verordnung unterliegenden Chemikalien. If necessary, the residual water content can be reduced by such conventional means as distillation under reduced pressure. Thus, an essential feature of the present invention is the discovery that by copolymerization of alkadiene and acrylamide monomers dissolved in a low molecular weight, liquid diol, a colloidal copolymer dispersion is obtained which can be readily intermixed with the liquid phenolic resole resins to give improved liquid phenolic resin compositions. PHENOL-FORMALDEHYDE AND EPOXY RESINS Nour-Eddine El Mansouri,a,* Qiaolong Yuan,a and Farong Huang a,* Besides polyurethanes and polyesters, phenolic and epoxy resins are the most prominent applications for technical lignins in thermosetting materials. By analysis the polymeric product contained 75 wt. About percent of the charged butadiene was consumed, but only about 30 percent of the acrylamide. A control adhesive was prepared concurrently using 100 parts of the same resole resin and 4 parts of benzenesulfonyl chloride. The InfoCard summarises the non-confidential data of a substance held in the databases of the European Chemicals Agency (ECHA). The resulting Water-insoluble liquid resin contained from 5 to 10% residual dissolved watenlt had a room temperature viscosity between about 200 and 500 cps. at room temperature is obtained. The choice of resin depends on the desired properties. CAS Number: 92-69-3. As a somewhat less active catalyst, an aromatic sulfonic acid or sulfonyl chloride such as p-toluenesulfonic acid or benzenesulfonyl chloride, is often used. The foam had a fine uniform pore structure, a density of 2.1 pounds per cubic foot, and :a displacementflexibility of 0.3 inch. It has now been discovered that copolymer dispersions prepared by copolymerizing alkadiene and acrylamide monomers in a low molecular weight, liquid diol are compatible with liquid phenol-formaldehyde resole resins and can be readily and uniformly intermixed therewith.

Usually an acidic catalyst is employed as a hardening agent. Harmonisation is based on the substance’s physical, toxicological and eco-toxicological hazard assessment. In general such resins are prepared by condensation of one mole of a monohydric phenol with between 1.0 and 2.5 and preferably between 1.40 and 1.50 moles of formaldehyde until a water-insoluble, liquid condensation product is obtained. Die Grenzwerte berufsbedingter Exposition (OEL-Werte) basieren auf zwei Rechtsrahmen, die integraler Bestandteil des EU-Mechanismus zum Schutz der Gesundheit der Arbeitnehmer sind. Additives such as sand, clay, carbon black, fiberglass and pigments are readily used in casting resin formulations with the modified phenolic resins. REACH registration dossiers have greater data requirements (such as supporting studies) than do notifications under CLP. When the desired polymerization has been obtained, the unreacted alkadiene is generally removed by evaporation to give a stable diol-copolymer dispersion which may be used directly without further treatment in the preparation of modified liquid phenolic resin compositions. About of the charged butadiene was polymerized. It is possible that a harmonisation is introduced through an amendment to the CLP Regulation. When this modified liquid phenol-formaldehyde resin composition is employed as an adhesive, greater flexibility and greatly improved bond strength are obtained. More particularly, alkadiene-acrylamide copolymers suitable for use in the process of this invention are prepared by the addition polymerization of an alkadiene monomer selected from the group consisting of 1,3- butadiene, isoprene and 2,3-dimethyl-1,3-butadiene with an acrylamide monomer having the general formula: wherein R is H or CH and R is H or a C -C alkyl group, using as a polymerization medium a liquid diol selected from the group consisting of: C -C alkylene glycols, and liquid polyalkyleneoxydiols having an average .molecular weight of less than 650 and the formula: HO(C,,H ,,O),,H wherein a is 2 or 3, and n is the average number of alkyleneoxy groups in the polymer.

It is a white crystalline solid that is volatile.The molecule consists of a phenyl group (−C 6 H 5) bonded to a hydroxy group (−OH). Preferably, however, low boiling liquids, such as aliphatic hydrocarbons, fluorocarbons, or ethers, having a boiling point in the range from about 20 to 100 C. are used to obtain lower density phenolic foams. 13. However, the viscosity of polalkyleneoxydiols having a molecular weight greater than about 650 is higher than desirable for efficient polymerization and dispersion of the resulting copolymers. Substances for which classification and labelling data have been notified to ECHA by manufacturers or importers. at room temperature; However, liquid phenolic resole resins having a viscosity in the range from about 200 to 1,000 cps.

To achieve the desired enhanced properties in the final cured phenolic resin product, only a relatively small amount of the copolymer/diol dispersion is required. For preparation of the modified phenolic resins described herein, it is preferable to use a water-insoluble liquid phenolic resole resin having a viscosity of from about 250 to 500 cps. Although alkadiene-acrylamide copolymers can be prepared from monomeric mixtures containing from about to 95 percent of the alkadiene monomer and a complementary amount of from about 95 to 5 percent of the acrylamide monomer, copolymers containing at least 50 percent by weight of polymerized alkadiene are required to prepare modified resole resins having the improved properties described. If no EU harmonised classification and labelling exists and the substance was not registered under REACH, information derived from classification and labelling (C&L) notifications to ECHA under CLP Regulation is displayed under this section. Properties of concern are calculated at four "levels" of certainty: The following properties of concern are calculated: The substance properties displayed in this section are derived from Harmonised classification and labelling (CLH) data, entries in the Candidate list of substances of very high concern for authorisation, the PBT assessment list, the ED assessment list, REACH registered dossier data and from notifications made under CLP.

Although they came into existence at the very start of the age of polymers, they continued to be developed into more and more applications. at 25 C. with a solids content of about 20 to 40 weight percent. or more are satisfactory. Particularly in liquid compositions to be used for phenolic foams, excessive amounts of diol can be detrimental to the physical properties, such as viscosity, required for preparation of a satisfactory foam. Modified phenolic resin compositions In the prepartion of liquid phenolic resin compositions modified by incorporating an alkadiene-acrlyamide copolymer-diol dispersion, it is particularly advantageous to employ a dispersion containing at least 10 weight percent, and preferably from about 20 to 50 weight percent of copolymer solids, to avoid addition of excessive amounts of the diol dispersant. Then the resinous product was washed thoroughly with water. Phenol-formaldehyde resin, also called phenolic resin, any of a number of synthetic resins made by reacting phenol (an aromatic alcohol derived from benzene) with formaldehyde (a reactive gas derived from methane ). Phenol-formaldehyde resoles and novalacs are cured at temperatures of from about 0° C. to about 150° C. and at pressures ranging from about atmospheric pressure to about 5 atmospheres to produce highly cross-linked resins when divinylbenzene is used as a cross-linking agent together with a minor amount of an acidic catalyst.
