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PETcISMA。PETcISMA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%。PETcISMA具有优良的结晶性能,θc为125~130 ℃,有利于通过控制结晶度改善材料的加工性能。同时,PETcISMA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 θg and θm 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 θc 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.
