异山梨醇-马来酸酐聚酯改性PET的研究
PET Modified with Copolyester of Isosorbide/Maleic Anhydride
摘要
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.关键词
