Abstract
Copolymers of ethylene with such monomers as an alkyl acrylate and carbon monoxide or with vinyl acetate alone are blended with a thermoplastic block-polyester elastomer and a tackifier to produce thermally stable, hot-melt adhesive compositions which adhere well to polyvinyl chloride and which retain adhesivity at elevated temperatures. Fillers, plasticizers and compatible waxes may also be present in the composition.
