摘要
以对苯二甲酸为主要原料 ,通过加入 2 %～ 1 5% (摩尔 )新戊二醇 ,合成了一系列不同二醇配比的共聚酯 ,用示差扫描量热方法研究了该体系的热性能。结果表明 。
The modified PET copolymers of different neopentyl glycol contents (2%～15%)were synthesized.Thermal property of these smaples was investigated by means of DSC.The results showed that both the melt point and crystallinity of the copolymers decreased with the increase of neopentyl glycol content in copolymer.
