Polycarbonate (PC) has good mechanical properties and good creep resistance, which is better than that of phthalamide and paraformaldehyde. Especially, PC modified by glass fiber has better creep resistance, so it can bear higher load at higher temperature and ensure dimensional stability. The main shortcomings of polycarbonate mechanical properties are easy to produce stress cracking, poor fatigue resistance, high notch sensitivity, no wear resistance and so on. PC has good high and low temperature resistance, good heat resistance at 120 ℃, and hot deformation temperature of 130 ~ 140 ℃. At the same time, it has good cold resistance, brittleness temperature is - 100 ℃, long-term service temperature is - 70 ~ 120 ℃. Moreover, its thermal conductivity and specific heat capacity are not high, its linear expansion coefficient is small, its flame retardancy is good, and it has self extinguishing property. As a weak polar polymer, PC has better electrical insulation although its electrical insulation is not as good as that of polyolefins. Because of its high glass transition temperature and low hygroscopicity, it can maintain good electrical properties under wide temperature and humidity conditions
PC是一种中等耐磨材料（但比金属好得多）。与尼龙、聚、氯化聚醚、聚等相比，但优于ABS、聚砜、**玻璃等。通过添加聚、玻璃纤维等填料，可以提高PC的耐磨性，降低摩擦系数和磨损损失，提高PV值。PC具有良好的耐热性和耐寒性。可在-100～130℃范围内长期使用。具有较高的载荷变形温度（130～140℃），受载荷影响较小。脆性温度在-100℃以下，即使在-180℃也不会像玻璃一样破碎。PC无明显熔点，在220～230℃熔融。由于高分子链的高刚性，其熔融粘度远**其他热塑性塑料
PC is a kind of polymer with carbonate group in the main chain, which is called polycarbonate. According to the structure of acetic acid group, PC can be divided into aliphatic, aromatic, aliphatic aromatic and so on. At present, the basic structure of commercial polycarbonate vinegar is aromatic. As a kind of amorphous thermoplastic resin with excellent comprehensive properties, it has excellent electrical insulation, extensibility, dimensional stability and chemical corrosion resistance, Polycarbonate vinegar is a kind of general engineering plastics with fast growth rate. At present, the industrial plant of polycarbonate vinegar basically adopts the process of interfacial polycondensation. The main process is to prepare bisphenol sodium salt from bisphenol and caustic soda solution, add human , and then send it into the reactor, After the reaction, the reaction liquid is sent to the polycondensation reactor, and the solution of caustic soda is added to carry out polycondensation reaction
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, 主要工艺是将双与溶液配制成双盐, 同时加人, 然后送人反应器内, 加人, 通进行化反应,反应完后将反应液送到缩聚反应器内, 加人和溶液, 进行缩聚反应.
