摘要
聚对苯二甲酸丁二醇酯(PBT)是重要的半结晶性热塑性聚酯,差别化的聚酯产品需要差别化的结晶性能。文章合成得到间苯二甲酸(IPA)含量0～20%改性PBT共聚酯样品,DSC分析表明改性共聚酯的结晶熔点及结晶熔融焓下降,且随IPA含量的增加近似呈线性减小。
Poly（butylene terephthalate）（PBT） is an important semi-crystallization thermoplastic polyester.Various uses of PBT require different crystallization characteristic.In this papers some samples of Poly（butylene terephthalate-co-isophthalate） with 0~20% isophthalate units contents have been prepared and their crystallization property has been analyzed by using DSC.The result shows that the crystallization melting temperature and melting enthalpy of copolyester reduces approximate-linearly with increasing of isophthalate unit content.
