    • PURPOSE: An ultra-high melt flow polycarbonate resin is provided to be able to remarkably improve the inherent mobility of polycarbonate resin without degrading the transparency or colors, and to be suitable to extrude a thin film light guide plate with a large size without changing the polymerization process. CONSTITUTION: An ultra-high melt flow polycarbonate resin includes 100.0 parts by weight of polycarbonate and 0.001-1 part by weight of phosphate-based polymer with a repeating unit of Chemical formula 1. In Chemical formula 1, A is a single bond, C1-5 alkylene, C1-5 alkylidene, C5-6 cycloalkylidene, -S- or -SO2-, R is substituted or non-substituted C6-20 aryl, R1 and R2 are substituted or non-substituted C1-6 alkyl, substituted or non-substituted C5-6 cycloalkyl, substituted or non-substituted C6-12 aryl or halogen, respectively, a and b are an integer of 0-4, independently, and n is an integer of 3-500.
    • 目的:提供超高熔点流动性聚碳酸酯树脂,能够显着提高聚碳酸酯树脂的固有迁移率,而不降低透明度或颜色,适合于挤出大尺寸的薄膜导光板,而不会改变 聚合过程。 构成:超高熔融流动性聚碳酸酯树脂包括100.0重量份聚碳酸酯和0.001-1重量份具有化学式1重复单元的磷酸酯基聚合物。在化学式1中,A是单键,C1 -5亚烷基,C 1-5亚烷基,C 5-6亚环烷基,-S-或-SO 2 - ,R是取代或未取代的C 6-20芳基,R 1和R 2是取代或未取代的C 1-6烷基,取代或 未取代的C5-6环烷基,取代或未取代的C6-12芳基或卤素,a和b分别为0-4的整数,n为3-500的整数。
