摘要
在用来自于玉米原料的乙二醇(EG)与对苯二甲酸(PTA)聚合得到的聚酯中,只有约三分之一的原料来自于可再生生物资源。如将聚酯原料中的部分对苯二甲酸也用来自于玉米工业的丁二酸(SA)来取代,就可制得一半原料来自于可再生生物资源的新型共聚酯。本文探索了这种共聚酯的合成方法、其结构和热性能。实验表明,当PTA与SA的摩尔比为1∶1时,所得到的共聚酯的熔点为117℃,玻璃化温度为56℃。该共聚酯有极好的拉伸性能和回弹性。
The raw materials used in corn from EG and PTA by polymerization of polyester, about one-third of the raw materials come from renewable biological resources. If the raw materials of polyester terephthalate with some also from the corn industry SA to be replaced by half the raw materials can be obtained from renewable biological resources in the new copolyester. This article explored the polyester synthesis, structure and thermal properties. Experiments show that： when the PTA and SA molar ratio of 1 ： 1, the melting point and glass transition temperature of copolymer obtained is 117 ℃ and 56 ℃ respectively. The copolyester is an excellent elasticity and tensile properties
