    • A polyester/polycarbonate blend is provided to solve the problem of degradation of transparency in the conventional polyester/polycarbonate blend while ensuring excellent heat resistance. A polyester/polycarbonate blend comprises: (a) a polyethylene terephthalate(PET) comprising terephthalic acid, ethylene glycol and C3-C6 alkylene glycol, or PET copolymerized with 1-10 mol% of isophthalic acid, cyclohexane dimethanol(CHDM) or diethylene glycol based on the acid or diol component; (b) a polycarbonate(PC); and (c) a high-CHDM glycol-modified PET containing CHDM coplymerized with the diol component in an amount of 20-80 mol%. The content of PC is 10-60 wt% based on the blend of PET(a)/PC, and the content of high-CHDM glycol-modified PET corresponds to a weight ratio of 0.2-2.5 based on PC.
    • 提供聚酯/聚碳酸酯共混物以解决常规聚酯/聚碳酸酯共混物中透明度降低的问题,同时确保优异的耐热性。 聚酯/聚碳酸酯共混物包括:(a)包含对苯二甲酸,乙二醇和C 3 -C 6亚烷基二醇的聚对苯二甲酸乙二醇酯(PET),或与1-10mol%间苯二甲酸,环己烷二甲醇(CHDM)或二甘醇 基于酸或二醇组分; (b)聚碳酸酯(PC); 和(c)含有20-80摩尔%的与二醇组分共混的CHDM的高CHDM二醇改性PET。 基于PET(a)/ PC的共混物,PC的含量为10-60重量%,高CHDM乙二醇改性PET的含量相对于PC为0.2-2.5重量比。
