摘要
研究了各种条件下聚酯 -酰胺的水解降解行为及其与结构之间的关系。结果表明 :酯键含量越高 ,质量损失就越快。聚合物的降解受酸、碱催化。根据SEM观察提出了可能发生的降解机理 :表面腐蚀、非晶区腐蚀、晶区破坏到全部降解。
The hydrolysis degradation behaviors of poly(ester amide)s(PEAs) were evaluated. Results showed that the degradation rate of PEAs increased with the content of ester block, and was catalyzed by acid or base. The SEM of the surface morphology of PEAs showed that the degradation proceeded from surface erosion, amorphous degradation then crystalline degradation.
