高耐热聚碳酸酯,制备方法,和由其形成的制品
摘要：
本申请公开一种聚合物共混物，其包括：第一聚碳酸酯，所述第一聚碳酸酯包括源自2-芳基-3，3-二(4-羟基芳基)苯并[C]吡咯酮的第一结构单元和源自二羟基芳族化合物的第二结构单元，并且所述第二结构单元与所述第一结构单元不相同，和第二聚碳酸酯，所述第二聚碳酸酯包括源自二羟基芳族化合物的结构单元；其中所述聚合物共混物的玻璃化转变温度为155至200℃；和其中厚度为3.2mm并且由所述共混物模制的试验制品的雾度为小于或等于2.6，根据ASTM D1003-00测量。本申请也公开了制备所述聚合物共混物的方法，以及由所述共混物制备的制品。
摘要（英）：

Disclosed herein is a polymer blend comprising a first polycarbonate comprising a first structural unit derived from a 2-aryl-3,3-bis(4-hydroxyaryl)phthalimidine and a second structural unit derived from a dihydroxy aromatic compound, wherein the second structural unit is not identical to the first structural unit, and a second polycarbonate comprising a structural unit derived from a dihydroxy aromatic compound, wherein the polymer blend has a glass transition temperature of 155 to 200 DEG C; and wherein a test article having a thickness of 3.2 mm and molded from the blend has a haze of less than or equal to 2.6 measured in accordance with ASTM D1003-00. A method of making the polymer blend, and articles prepared from the blend, are also disclosed.
