Summary: | The present invention provides a transparent impact resistant polyester composition. The polyester composition comprises 100 parts by weight of polyester, and 0.1 to 6.0 parts by weight of styrene butadiene block copolymer, wherein a molecular weight of the styrene butadiene block copolymer is in the range from 100,000 to 200,000, and an intrinsic viscosity of the styrene butadiene block copolymeris in the range from 0.1 to 0.6.
本发明提供种透明且具有耐冲击性的聚酯组合物,其组成含有100重量份的聚酯,以及0.1至6.0重量份的苯乙烯-丁二烯嵌段共聚物(styrene butadiene block copolymer),其中苯乙烯-丁二烯嵌段共聚物的分子量在100,000至200,000之间,且其特性黏度(intrinsic viscosity)在0.1至0.6之间。本发明提供具有耐冲击性质的聚酯组合物,藉由加入非直链型SBC,所制得的聚酯片材透明性佳,且低温耐寒性优异。 |
