354-2229(8CW-5144) ABSTRACT OF THE DISCLOSURE Compositions comprising polyetherester resins, polyetherimide ester resins alone or combined with polyester resins, and mixtures of any of them or of polyester resins alone with copolymers of alpha-olefins and vinyl esters of aliphatic monocarboxylic acids have improved elastomeric character. For example, addition of 50 and 30 parts by weight of a vinyl acetate-ethylene copolymer having a high content of units derived from vinyl acetate to a polyetherimide ester copolymer considerably improves compressibility, elasticity, low temperature impact strength, UV light resistance and chemical resistance. Articles shaped from such compositions show desirably lower hardness, improved dynamic fatigue properties, paintability, extrudability and injection moldability. 3542229A
