Title
(EN) REDUCED COLOR POLYCARBONATE COMPOSITIONS, METHODS OF MANUFACTURE, AND ARTICLES THEREOF
(ZH) 减少颜色的聚碳酸酯组合物及其制备方法和制品
Abstract
(EN)
A method of preparing a polycarbonate composition, including: melt polymerizing in a polymerization unit a dihydroxy compound with a diaryl carbonate and removing a stream of color inducing species containing an isopropenyl phenyl-containing group from the polymerization unit, to form a polycarbonate composition, wherein the polycarbonate has a color inducing species containing an isopropenyl phenyl-containing group level below 170 ppm is provided.

(ZH)
提供了制备聚碳酸酯组合物的方法,包括:在聚合单元中使二羟基化合物与碳酸二芳酯熔融聚合,并从聚合单元中去除包含含有异丙烯基苯基的基团的诱发颜色物质流股,以形成聚碳酸酯组合物,其中该聚碳酸酯的包含含有异丙烯基苯基的基团的诱发颜色物质的水平低于170ppm。
