Abstract
Abstract Cross-linkable vinyl ester and/or vinyl halide copolymers containing hydroxyl groups consisting essentially of: (a) from 50% to 99% by weight of monomer units selected from the group consisting of vinyl esters of alkanoic acids having from 1 to 18 carbon atoms, vinyl halides, and mixtures of said vinyl esters and vinyl halides, (b) from 0 to 40% by weight of mono-olefinically-unsaturated monomer units copolymerizable with vinyl esters and vinyl halide, (c) from 1% to 50% by weight of allyl ester monomer units of the formula: ##STR1## wherein R 1 and R 2 are selected from the group consisting of hydrogen and alkyl having from 1 to 16 carbon atoms, and R 3 is alkylene having from 1 to 16 carbon atoms, with the proviso that the total number of carbon atoms in R 1 , R 2 and R 3 is at least 2, where said copolymer has a K-value of between 10 and 100.
