PC是分子主链中含有碳酸酯基的聚合物统称为聚碳酸酯,根据醋基结构可分为脂肪族、芳香族、脂肪族一芳香族等多种类型。目前商业化聚碳酸醋的基本结构为芳香族代。由于代是一种综合性能优良的非晶型热塑性树脂, 具有优异的电绝缘性、延伸性、尺寸稳定性及耐化学腐蚀性, 较高的耐热性和耐寒性还具有自熄、易增强、阻燃、无毒、卫生、能着色等优点,聚碳酸醋是增长速度快的通用工程塑料,目前聚碳酸醋的工业化装置基本上都是采用界面缩聚法工艺, 主要工艺是将双酚与烧碱溶液配制成双酚钠盐, 同时加人酚, 然后送人反应器内, 加人二氯甲烷, 通进行化反应,反应完后将反应液送到缩聚反应器内, 加人和烧碱溶液, 进行缩聚反应.
The production of PC resin is mainly concentrated in the United States, Western Europe and Japan. The production capacity of these three regions accounts for about 90% of the world's total production capacity. At present, the development of polycarbonate industry in the world presents two major characteristics. One is that production tends to be more centralized and monopolized. The production capacity of Bayer company, Ge chemical company, Dow Chemical Company and 13 bendi company account for about 80% of the world's total production capacity. Among them, Ge electric gas, Bayer, Dow Chemical and Japan's Diren company respectively account for the world's total production capacity in 2000 35%, 31%, 9% and 9% of production capacity. These companies control the world's polycarbonate production technology and dominate the world polycarbonate market. Second, Asia is develo rapidly. In recent years, with the gradual recovery of Asian economy, especially the sustained and rapid development of China's economy, the demand for engineering plastics is becoming stronger and stronger. World famous polycarbonate manufacturers have also come to Asia to invest and build factories.
PC在工程上具有实用,其中产量,用途广而又早实现工业化生产的则是双酚A型PC,其特点是原料价格低廉,加工性能及制品性能**群,合成双酚A型PC有多种方法,但目前工业生产中采用的主要是法和酯交换法,纯PC树脂是一种无定形、无味、无臭、无毒、透明、呈微、白色或无色的刚而韧的热塑性聚合物;相对分子质量一般在2~7万;燃烧时慢燃,离火后慢熄,火焰呈,燃烧后熔融、起泡,发出的花果臭气味,PC综合性能优良,是重要的工程塑料.
PC属中等耐磨材料( 但比金属还是要好很多)。比尼龙、聚、氯化聚醚及PTFE差,但比ABS、聚砜、**玻璃等好。在PC中加入某些填料可改善耐磨性,例如加入PTFE、玻纤等可降低摩擦系数和磨损量,提高PV值。PC的耐热性和耐寒性都很好,长期使用温度的范围较宽,可在-100~130℃范围使用,其负荷变形温度高(130~140℃),且受负荷影响小;脆化温度在-100℃以下,甚至在-180℃的低温下,也不会象玻璃那样破碎。PC没有明显的熔点,在220~230℃呈熔融状态。由于大分子链刚性大,其熔融粘度比其它热塑性塑料高得多.
