化学和性能

1。工业生产的聚碳酸酯是通过双酚A和光气的界面缩聚过程进行反应的
该反应在水相和有机相存在的碱性条件下进行。分子量由酚链终止剂控制。双酚A聚碳酸酯的生产过程因界面反应和产品回收而复杂

2。韧性是聚碳酸酯最突出的性能，可用于学校窗户、防暴器材和体育器材
结构中的碳酸盐段使聚碳酸酯成为最坚韧和耐用的塑料之一，而双酚A段使聚合物具有较高的热性能（Tg=300F）。典型商用聚碳酸酯的分子量为22000-35000，多分散性（MW/MN）一般为2.2-2.5

3。聚碳酸酯（ASTM D 1238，573F，1.2 kg）的熔体流动速率通常有一定的范围。标准商品的熔体流动范围为4-23
超过此熔体流动范围，除流变性能外，其他性能相当稳定。在较高的熔体流动速率下，只有缺口伊佐德冲击强度略有下降

Chemistry and performance

1. The industrially produced polycarbonate is reacted by the interfacial polycondensation process of bisphenol A and phosgene.
This reaction is carried out under alkaline conditions in the presence of an aqueous phase and an organic phase. The molecular weight is controlled by using a phenolic chain terminator. The process of producing bisphenol A polycarbonate is complicated due to interfacial reactions and product recovery.

2. Toughness is the most outstanding performance of polycarbonate, which can be used in school windows, anti-riot equipment and sports equipment.
The carbonate segment in the structure makes polycarbonate one of the most tough and durable plastics, while the bisphenol A segment makes the polymer have high thermal properties (Tg=300F). The molecular weight of typical commercial polycarbonate is 22 000-35 000, and the polydispersity (MW/MN) is generally 2.2-2.5.

3.The melt flow rate of polycarbonate (ASTM D 1238, 573F, 1.2 kg) generally has a certain range. The melt flow range of standard commodities is 4-23.
Beyond this melt flow range, other properties are quite stable except for rheological properties. Only the notched Izod impact strength decreases slightly at higher melt flow rates.
