Due to the non crystallinity of polycarbonate, the packing between molecules is not compact enough. The organic solvents of aromatic hydrocarbon and chlorinated hydrocarbon can make it swell or dissolve, which is easy to cause solvent cracking. The alkali resistance is poor.
PC光学性能 聚碳酸酯是非结晶性物质,纯净聚碳酸酯无色透明,具有良好的透光性,因其表面硬度较差,耐磨性不好,表面容易发毛而影响其透光
PC mechanical properties: polycarbonate has excellent mechanical properties, especially its impact strength and dimensional stability. It is difficult to maintain high mechanical strength in a wide temperature range. Its disadvantages are poor fatigue strength and wear resistance, and easy to produce stress cracking.

尽管PC具有许多优能,然而由于PC分子链的高刚性和大的空间阻位使其具有较高的熔体粘度,因此加工困难,易开裂,耐溶剂性和耐磨损性较差,因此对PC改性研究成为PC应用研究重要的课题,目前聚合物合金化成为PC改性重要途径,国外已有大量性能优良PC合金投入市场,随着PC合金材料的研究不断进展,PC的应用范围不断扩大,
PC开发前景的应用领域,宽波透光的光学器械,作为一种透明性能良好的工程塑料,PC作为光盘基材在全球大量使用, 不仅可以制备CD、VCD、DVD光盘,还可以适用于高密度记录光盘的基材, PC片材特别适宜于制作眼镜镜片,在PC分子链中引入硅氧基团,可以提高其硬度及耐擦伤性。PC作为高折射率塑料,用于制作耐高温光学纤维的芯材
