Graft copolymers are made in which the substrate polymers are diene rubbers and the superstrates are polymers containing hydroxyl groups. The graft copolymers are preferably made by the polymerization of monomers containing hydroxyl groups in latices of diene rubbers. The graft copolymers possess adhesion to a variety of substrates and may be used in blends with other resinous materials in the manufacture of laminates. The examples describe making graft polymers by polymerizing: (1-3) styrene, acrylonitrile and vinyl benzyl alcohol in polybutadiene and butadiene-divinyl-benzene and butadiene-styrene-divinylbenzene copolymer latices, (4) styrene, acrylonitrile and 2-phenyl allyl alcohol in a butadiene-styrene-divinylbenzene copolymer latex, (5) styrene, acrylonitrile and vinyl benzyl alcohol in a butadiene - styrene - vinyl benzyl alcohol copolymer latex, (6 and 8) styrene, acrylonitrile and 2-phenyl allyl alcohol in butadiene-styrene-2-phenyl allyl alcohol-divinylbenzene copolymer latices, (7) styrene, acrylonitrile and vinylbenzyl alcohol in butadiene-vinylbenzyl alcoholdivinylbenzene copolymer latex, (9) styrene and vinylbenzyl alcohol in a butadiene-styrene-divinylbenzene copolymer latex, (10) styrene and 2-phenyl allyl alcohol in a butadiene-styrene-divinylbenzene copolymer latex, (11) vinylbenzyl alcohol in a butadiene-styrene-divinylbenzene copolymer latex, (12) 2-phenyl allyl alcohol in a butadiene-divinylbenzene copolymer latex, (13) 2-hydroxymethylbutadiene in an isoprene-styrene-divinylbenzene copolymer latex, (14) styrene, acrylonitrile and vinylbenzyl alcohol in a butadiene-acrylonitriledivinylbenzene copolymer latex, (15) ethyl betahydroxyethyl fumarate and vinyl chloride in a butadiene - styrene - divinylbenzene copolymer latex, (16) methyl methacrylate and bis-(betahydroxyethyl) fumarate in a butadiene-styrene-divinylbenzene copolymer latex, (17) ethyl acrylate and beta-hydroxyethyl acrylate in a butadiene - styrene - divinylbenzene copolymer latex, (18) butene-1 and ethyl beta-hydroxyethyl fumarate in a butadiene-styrene-divinylbenzene copolymer latex, (19) butadiene and 2-phenylallyl alcohol in a butadiene-styrene-divinyl benzene copolymer latex and (20) butadiene and vinyl benzyl alcohol in a butadiene -styrene-vinylbenzyl alcohol copolymer latex. The graft copolymers of Examples (3) and (9) are converted into dispersions in methyl ethyl ketone and the dispesions are blended with a styrene-maleic anhydride copolymer and an epoxy resin to form syrups which are used in forming laminates with glass cloth.
