Abstract
Thermoplastic polymer compositions comprise a thermoplastic copolyether-ester elastomer, a rubber graft polymer and a rigid polymer. The rigid polymer is formed from one or more monomers selected from styrene, .alpha.-methyl styrene and halogen-substituted styrenes, at least 20 weight percent acrylonitrile, and N-phenyl maleimide, and is included in the compositions to provide improved impact strength and tensile elongation without significantly deteriorating other physical properties of the compositions.
