    摘要: A composition comprisingA. 24-70% by weight of an unsaturated crystalline polyester which is the condensation product of fumaric acid and a glycol of the formulaHO--CH.sub.2 --R--CH.sub.2 --OHwherein R is of the formula (CH.sub.2).sub.z wherein z is 1 to 18 or a symmetrical dialkyl derivative of (CH.sub.2).sub.z wherein the alkyl substituents are situated on the same carbon atom or cycloalkylene,B. 20-70% by weight of styrene andC. 1-30% by weight of at least one member selected from the group consisting of a polycarbonate, polyamide, polyvinyl alcohol, polyvinyl alcohol acetal, polyvinylchloride, cellulose ester of at least one organic acid and polyethylene. Said mixture may additionally contain one or more fibrous reinforcing agents and one or more fillers.
