PC是分子鏈中含有碳酸酯基的高分子聚合物,根據(jù)酯基的結(jié)構(gòu)可分為脂肪族、芳香族、脂肪族-芳香族等多種類型。其中由于脂肪族和脂肪族-芳香族聚碳酸酯的機(jī)械性能較低,從而限制了其在工程塑料方面的應(yīng)用。目前芳香族聚碳酸酯獲的了工業(yè)化生產(chǎn)。由于聚碳酸酯結(jié)構(gòu)上的特殊性,現(xiàn)已成為五大工程塑料中增長(zhǎng)速度快的通用工程塑料。 聚碳酸酯也叫聚碳酸脂(Polycarbonate)常用縮寫PC
是一種韌的熱塑性樹脂,通常是由雙酚A和生產(chǎn)的,現(xiàn)在也開發(fā)了不使用的生產(chǎn)方法,并已在20世紀(jì)60年代初實(shí)現(xiàn)工業(yè)化,90年代末實(shí)現(xiàn)大規(guī)模工業(yè)化生產(chǎn)。現(xiàn)在產(chǎn)量?jī)H次于聚酰胺的第二大工程塑料。其名稱來源于其內(nèi)部的CO3基團(tuán)。

PC is a polymer molecular chain containing a carbonate group,according to the ester structure can be divided into aliphatic,aromatic, aliphatic, aromatic and other types of. Due to themechanical properties of aliphatic and aliphatic aromatic polycarbonate is low, which limits its application in engineeringplastics. At present only aromatic polycarbonate byindustrialized production. Due to the particularity ofpolycarbonate structure, has become the fastest growing general engineering plastic five major engineering plastics.Polycarbonate is also called polycarbonate (Polycarbonate)commonly abbreviated PC
Is a tough thermoplastic resin, are usually produced bybisphenol A and phosgene, method of production aredeveloped without using phosgene, and has achieved industrialization in the early nineteen sixties, the late 90's to realize large-scale industrialized production. The second major engineering plastics production is now second only to thepolyamide. Its name comes from its internal CO3 groups.
