摘要：
A thermally self-cross-linkable ethylene/vinyl acetate copolymer consisting essentially of the following monomer units:A. from 5 to 50% by weight of ethylene,B. from 30 to 87% by weight of vinyl acetate,C. from 2 to 10% by weight of a copolymerizable compound containing an N-methylol group,D. from 5 to 20% by weight of an acryl compound selected from the group consisting of alkyl acrylate and alkyl methacrylate where alkyl has from 1 to 10 carbon atoms,E. from 0.5 to 3% by weight of a mono-olefinically-unsaturated carboxylic acid, andF. up to 1% by weight of a poly-olefinically-unsaturated monomer, and having a glass transition temperature of between -40.degree. and +10.degree. C; as well as the process for its preparation.
