Abstract

1349569 Epoxy resin composition E I DU PONT DE NEMOURS & CO 3 May 1971 12695/71 Heading C3B A composition comprises: (A) 5-40% of a polymer containing epoxy radicals which is obtained by reacting (I) at least one polymer selected from (a) copolymers of 5-45% by wt. acrylonitrile and 55-95% by wt. of butadiene; (b) acrylic polymers which are (i) homopolymers of CH 2 = CHCOOR (R = C 2-8 alkyl) or (ii) copolymers of up to 30% by methyl methacrylate and monomers CH 2 = CHCOOR<SP>1</SP> (R<SP>1</SP> = C 4-8 alkyl) or mixtures of polymers (i) and (ii); (c) polyesters or (d) polyalkylene ethers; (a), (b), (c) and (d) each contain an average of more than one OH, SH, COOH, COCNHNH 2 or NHR<SP>11</SP> radical (R<SP>11</SP> = H or C 1-6 alkyl) at least one of said radicals being in a terminal position, each have a M.W. >1000 if the polymer is a polyalkylene ether or >2000 if the polymer is an acrylonitrile/butadiene copolymer, an acrylic copolymer or a polyester, a glass transition temp. <25‹ C. and a solubility parameter of 8-10À5; and (II) at least one epoxy resin containing an average of at least 1À5 epoxy radicals per molecule, at a temperature sufficient to produce the polymer containing epoxy radicals; and (B) 95-60% by wt. of an epoxy resin having an average of at least 1À5 epoxy radicals per molecule; and (C) 0À5-60% by wt. of a filler, e.g. glass microballoons. The percentages of (A), (B) and (C) are based on their combined weight. The polymers (I) used in preparing (A) may contain on average 1À3 to 3 of the specified radicals per molecule. The epoxy resin may be a diglycidyl ether of bisphenol A. The compositions may be cured using conventional epoxy resin curing agents. Uses.-Coatings, adhesives, for repairing damaged car bodies.
