Polyvinyl chloride, polycarbonate and copolyester compositions and articles made using these compositions

The present disclosure relates to a novel polyvinyl chloride composition containing a polyvinyl chloride resin, a polycarbonate resin, and a copolyester resin. More specifically, the present disclosure relates to a polyvinyl chloride composition comprising a mixture of a polycarbonate and a high glass transition temperature (Tg) copolyester to increase the Tg and heat distortion temperature under load (HDTUL) of the polyvinyl chloride composition. 本公开涉及含有聚氯乙烯树脂、聚碳酸酯树脂和共聚酯树脂的新型聚氯乙烯组合物。更具体地说，本公开涉及聚氯乙烯组合物，其包含聚碳酸酯和高玻璃化转变温度(Tg)共聚酯的混合物，以提高聚氯乙烯组合物的Tg和载荷下热变形温度(HDTUL)。
