A polyester composition comprising (a) an aromatic polyester having a relative viscosity of 1.2 to 20, (b) an aromatic polycarbonate having a number-average molecular weight of 10,000 to 80,000, and (c) a glycidyl group- containing copolymer of 0.1 to 100 in melt index containing as major components an α-olefin and a glycidyl ester of an a, ε-unsaturated acid. This composition possesses excellent fluidity and residence stability upon molding, and excellent mechanical properties, particularly impact resistance, thus being useful as electric and electronic device parts and automobile parts. This composition can be molded into various moldings in a conventional manner.
一种聚酯组合物,包括:(a) 相对粘度为 1.2 至 20 的芳香族聚酯;(b) 数均分子量为 10,000 至 80,000 的芳香族聚碳酸酯;(c) 熔体指数为 0.1 至 100 的含缩水甘油基的共聚物,其主要成分为 α-烯烃和 a,ε-不饱和酸的缩水甘油酯。 这种组合物在成型时具有优异的流动性和停留稳定性,以及优异的机械性能,尤其是抗冲击性,因此可用作电子电气设备零件和汽车零件。 这种组合物可以常规方式成型为各种模具。
