Each joint was then clamped securely and cured by heating overnight in an oven held at 75 C. The adhesive strength of the cured joints Was determined with an Instron test machine. R. BARON, Assistant Examiner. Emulsifying and suspending agents are not usually required as the diol diluent itself is an extremely effective polymerization medium. 260-79.3 3,262,897 7/1966 Kordzinski et a1. percent polymerized butadiene and 23 wt. A hard, infusible, and chemically resistant plastic, Bakelite was based on a chemical combination of phenol and formaldehyde (phenol-formaldehyde resin), two … 16 The liquid phenolic adhesive of claim 15 wherein the copolymer is a copolymer of 1,3-butadiene and acrylamide. Substances indicated, in 2009, as being intended to be registered by at least one company in the EEA. ECHA has no public registered data on the routes by which this substance is most likely to be released to the environment. percent of polymerized butadiene have been prepared using ethylene glycol, diethylene glycol, or a polyethyleneoxydiol having an average molecular weight of 600 as a polymerization medium. Particularly desirable copolymers are obtained from a monomeric mixture consisting essentially of from 50 to 90 weight percent of 1,3-butadiene and from 50 to 10 weight percent of acrylamide or methacrylamide. The criticality of formulation is indicated by the failure of a standard phenolic foam formulation modified by incorporation of as little as 0.5 weight percent of a liquid butadiene-acrylonitrile rubber. Here you can find all of the regulations and regulatory lists in which this substance appears, according to the data available to ECHA. This invention relates to an improved phenol-formaldehyde resin composition and a process for its preparation. in British Patent 578,846. This is why novolacs (F:P <1) do not harden without the addition of a crosslinking agents, and why resoles with the formula F:P >1 will. If the substance was not covered by the EC Inventory, ECHA attributes a list number in the same format, starting with the numbers 6, 7, 8 or 9. The CLP Regulation uses the UN Global Harmonised System (GHS) and European Union Specific Hazard Statements (EUH). Although a number of other rubber-modified phenol aldehyde resins have been described, liquid phenolic resole resin compositions containing a uniformly intermixed, compatible-rubbery copolymer of alkadiene and acrylamide monomers have not been described. 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. monomer having the formula: wherein R is H or CH and R is H or C -C alkyl, in.

EXAMPLE 2 Butadiene-acrylamt'de copolymer (A) A mixture of 20 parts of 1,3-butadiene, 20 parts of crystalline acrylamide, 0.2 part of potassium persulfate, and 110 parts of ethylene glycol was placed in a sealed glass pressure bottle and shaken for 18 hours in a constant temperature bath at 70 C. The mixture was then cooled to room temperature and the bottle vented to release unreacted butadiene. Die Härtungsmittel sind Reaktionspartner und bilden zusammen mit dem Harz den makromolekularen Kunststoff. (Cl. Damit Sie die Website optimal nutzen können, verwenden wir Cookies. For example, Young and Newberg in United States Patent 2,657,185, describe blending of a copolymer of an alkadiene and an acrylonitrile with a modified phenolic resin obtained from a C -C alkyl-substituted phenol by using a differential rolling mill to break down the rubbery copolymer and then to blend in the liquid or solid phenolic resin. Unless otherwise stated, all parts and percentages are by weight. percent polymerized butadiene and 20 wt. Test sheets of each modified resin were prepared by casting a thin 0.140 inch coating of resin on a glass plate and allowing the casting to cure at room temperature for at least 2 weeks. At times a higher amount of up to about 20 percent of the copolymer dispersion may be advantageous. REACH registered substance data was upgraded on 9th November. More information about Classification and Labelling is available in the Regulations section of ECHA website. In some applications a mixture of an aromatic sulfonic acid and a dior trichloroacetic acid is particularly effective. We apologise for the inconvenience in the meantime. For each foam several test specimens are used to obtain an average value of this flexibility.

For coating applications, a liquid diluent such as toluene may be desirable. A substance may have its use restricted to certain articles or products and therefore not all the examples may apply to the specific substance. The ‘Hazard classification’ and labelling section uses the signal word, pictogram(s) and hazard statements of the substance under the harmonised classification and labelling (CLH) as its primary source of information. Alibaba.com offers 647 phenolic formaldehyde resin powder products. 215–540–4, is covered by three harmonisations: 005–011–00–4; 005–011–01–1 and 005–011–02–9), CLH information cannot be displayed in the InfoCard as the difference between the CLH classifications requires manual interpretation or verification. Polymerization was allowed to continue for another 3 to 4 hours at about 40 C. until a viscous water-insoluble liquid resole resin was obtained. 4-Phenylphenol. The phenolic compounds in these resins are derived primarily from petrochemical sources. More particularly, it is related to a liquid thermosetting phenol-formaldehyde resole resin composition containing therein a minor amount of a compatible alkadieneacrylamide copolymer. About of the charged butadiene was polymerized. the products in which the substance may be used) may refer to uses as intermediate and under controlled conditions, for which there is no consumer exposure.

Also in the amounts normally present, the low molecular weight diol is not detrimental in the resin compositions. For example, polymerization of a 50/50 weight percent mixture of 1,3-. butadiene/acrylamide in ethylene glycol at 70 C. gave a copolymer containing about 75 weight percent polymerized butadiene and 25 weight percent polymerized acrylamide. The control samples had an average break strength of 800 p.s.i. These modified compositions can be advantageously employed in the preparation of a great variety of resinous phenolic products such as castings, adhesive joints, foams, coatings, etc. In approximate order of decreasing consumption, products generated from formaldehyde include urea formaldehyde resin, melamine resin, phenol formaldehyde resin, polyoxymethylene plastics, 1,4-butanediol, and methylene diphenyl diisocyanate. Such modified phenolic resole compositions give after curing thermoset resinous products having improved resiliency, flexibility and strength. Although the alkadiene-acrylamide copolymer can be recovered from the diol dispersion by coagulation with water, it is not desirable in the practice of the invention. Incorporating or blending of small amounts of synthetic or natural rubbers with an uncured phenolformaldehyde resin has often been recommended to improve fiexibility and shock resistance of the cured product. Furthermore, some substances can be found in an article, but with unlikely exposure (e.g. The modified pehnolic resin compositions can be formulated as desired with many conventional additives, mixed with standard catalysts, and then cured to give thermoset phenolic resinous products having improved resiliency, strength, and stability. Then standard test strips were cut from each cured sheet and used to measure the flex strength by standard methods. 11. Alternate sources of phenolic compounds in-clude tannins, lignins, biomass pyrolysis products, and coal gasification products.
