摘要

通过熔融酯化反应制备了乙烯－乙烯醇-g-丙烯酸（EVOH-g-AA）共聚物，用红外光谱对接枝产物进行了表征。凝胶抽提结果显示，由于乙烯基双键的引入，难于辐射交联的EVOH在较低的吸收剂量下就可以辐射交联。改性EVOH与聚乳酸共混物的辐射效应研究结果表明，聚乳酸进入交联网格，说明改性EVOH具有一定的强化辐射交联剂的作用。

Abstract

Ethylene-vinyl alcohol-g-acrylic acid (EVOH-g-AA) copolymer was prepared by melt esterification reaction. FTIR was used to characterize the graft product. Gel extraction results show that EVOH-g-AA becomes easier to be cross-linked by radiation at low absorbed doses, which is different with neat EVOH due to the introduction of vinyl double bond. From the study of irradiated effect of PLA/ EVOH-g-AA blends it has been found that PLA could enter the crosslinking network. So the EVOH-g-AA could be used as enhance radiation cross-linking agent.
