This substance is used by consumers, by professional workers (widespread uses), in formulation or re-packing and at industrial sites. 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. United States Patent 3,336,243 PHENOL-FORMALDEHYDE RESIN COMPOSITION Walter L. Garrett, Freeland, Mich., assignor to The Dow Chemical Company, Midland, Mich., a corporation of Delaware N0 Drawing. (B) A complementary amount of about 50-5 weight percent of an acrylamide monomer having the formula wherein each a is 2 or 3 and n is a number such that the diol has a molecular weight of less than 650. Phenolharze (PF-Harze, Phenol-Formaldehyd-Harze) sind Kunstharze (Kondensationsharze), die durch Polykondensation aus Phenolen und Aldehyden hergestellt werden. No. EXAMPLE Casting resins Using a standard formulation: 100 parts of liquid phenol-formaldehyde resole resin. 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. This substance has been found in the following regulatory activities (directly, or inheriting the regulatory context of a parent substance): Die ECHA bietet zahlreiches Online-Material in Ihrer Sprache an, ein Teil dieser Seite liegt jedoch nur auf Englisch vor.
