Reinforced, molding compositions having improved ductility and melt flow properties comprise a cyclo aliphatic polyester resin preferably comprising the reaction product of a cycloaliphatic C6-C12 diol or chemical equivalent and C6-C12 cycloaliphatic diacid or chemical equivalent, a high molecular weight polyetherester polymer which increases the melt flow properties of the polyester polymer without reducing the ductility thereof, a glass filler to reinforce and stiffen the composition and optionally an impact modifying amorphous resin which increases the ductility of the polyester resin but reduces the melt flow properties thereof.
具有更好的延展性和熔体流动性能的增强型模塑组合物包括:环脂族聚酯树脂(最好包括环脂族 C6-C12 二醇或化学等效物与 C6-C12 环脂族二酸或化学等效物的反应产物)、高分子量聚醚酯聚合物(可增加聚酯聚合物的熔体流动性能,但不会降低其延展性)、玻璃填料(可增强组合物的强度和刚度)以及抗冲击改性无定形树脂(可增加聚酯树脂的延展性,但会降低其熔体流动性能)。
