耐水解生物降解聚酯PBAT的制备及性能研究
Preparation and characterizations of hydrolysis-resistant biodegradable PBAT
摘要
Abstract
PBAT/polycarbodiimide(PCDI)and PBAT/carbodiimide(CDI)blends were prepared through melt blending using CDI and PCDI as anti-hydrolysis agents,and the effect of the content of anti-hydrolysis agent on the thermal,me-chanical,molecular weight,and hydrolysis behavior of PBAT was investigated.The results indicated that PCDI exhibit-ed a remarkable efficacy on enhancing the hydrolysis resistance of PBAT,resulting in a significant reduction in the content of carboxyl end groups from 28.2 to 0.4 mol/t when 1.5 wt%PCDI was incorporated.The PBAT samples without any anti-hydrolysis agents showed a hydrolysis weight loss of 7.54 wt%after hydrolysis at 70 ºC for 1 051 h.The hydrolysis weight losses of the samples containing 0.5,1.0,and 1.5 wt%PCDI was 6.71%,4.34%and 0.55%,respectively.关键词
