| 摘 要： | 使用异山梨醇马来酸酐聚酯改性聚对苯二甲酸乙二醇酯（PET），通过反应性挤出的方法制备了PETcISMA。PETcISMA具有与PET接近的玻璃化温度和熔点，而且为一相结构，在不影响PET热性能的前提下，最大填入量可达30%。PETcISMA具有优良的结晶性能，θc为125~130 ℃，有利于通过控制结晶度改善材料的加工性能。同时，PETcISMA也具有更好的耐水性能、耐酸碱性和生物降解性。

| Abstract: | PET-c-IS-MA was prepared from PET which modified by copolyester of isosorbide/maleic anhydride through reactive extrusion. PET-c-IS-MA had the similar θg and θm as that of PET and a single phase structure from thermal gravity analysis. PET-c-IS-MA with the maximum amount of 30% IS-MA could remain the thermal properties of PET. PET-c-IS-MA shows higher crystal property than PET for the presence of θc from 125 ℃ to 130 ℃, and hence improved the process characteristics by changing the crystal degree of PET-c-IS-MA. Moreover, PET-c-IS-MA possessed higher water resistance, better stability in acid or alkaline medium and biodegradation. |
