    Abstract: A resin-like product having a degree of hydrolysis of 50 to 70 mole percent is obtained by selective alcoholysis of a vinyl ester copolymer, if desired in the form of a mixture with a vinyl ester homopolymer. The starting material employed is preferably a vinyl acetate/crotonic acid copolymer. The resin is suitable for use as a hot-melt adhesive which forms coherent films capable of being activated by water or water vapor.

    Abstract: Thermoplastic composition having high cohesion and a reduced tendency to flow, based on a copolymer of ethylenically unsaturated monomers obtained by conventional methods in the presence of polymerization initiators and a chelating agent based on(A) a copolymer consisting of an alkyl ester of an .alpha., .beta.-ethylenically unsaturated mono- and/or dicarboxylic acid with 1 to 12 carbon atoms in the alcohol group, an amide of such an acid, unsubstituted at the nitrogen atom, one of these acids themselves and optionally another copolymerizable monomeric compound,(B) a metal-containing cross-linking agent, the metal atom being an element of the second, third or fourth group of the Periodic Table,and optionally(C) other additives acting as extenders and other conventional additives,and the preparation thereof by treating the copolymer (A) together with the cross-linking component (B) and possibly the other additives (C) in a mixing apparatus at 100.degree. to 150.degree. C., during which cross-linking of the copolymer occurs. The thermoplastic compositions may be used as thermoplastic and hot-melt adhesives, laminating adhesives, sealable coatings, adhesive or barrier layers.
