热稳定的聚碳酸酯、其热塑性组合物以及由其制成的制品
摘要：
一种诸如脂族/芳族聚碳酸酯的聚碳酸酯，其包括化学式(H－1)的碳酸酯重复结构单元，化学式(H－1)中Rh是具有化学式(H－2)的基团，化学式(H－2)中R11、R12、R13、R14、R15、R16、R17、R18、R19、R20、R21、R22、R23、R24、R25、R26、R27和R28中的每一个独立地为氢、C1－C6烷基或卤素取代的C1－C6烷基。该聚碳酸酯及其热塑性组合物具有提高的热稳定性，成本低廉，并且表现出改善的加工性能，例如最少的环状碳酸酯形成量以及最少的胺受体需求量。
摘要（英）：

A polycarbonate such as aliphatic/aromatic polycarbonate comprises repeating structural carbonate units of the formula (H-I): in which R is a radical having the formula (H-2): wherein each of R11, R12, R13, R14, R15. R16, R17, R18, R19, R20, R2I, R22, R23, R24, R25, R26, R27, and R28 is independently a hydrogen, a C1-C6 alkyl group, or a halogen substituted C1-C6 alkyl group. The polycarbonate, and a thermoplastic composition thereof, have improved thermal stability, cost-effectiveness, and exhibit improved manufacturability such as, for example, minimum cyclic carbonate formation and minimum amine acceptor requirement.
