摘　　要：通过酯化反应制备了乙烯-乙烯醇-丙烯酸(EVOH-AA)接枝型材料,并用红外光谱对接枝产物进行了表征。凝胶抽提结果表明,由于乙烯基双键的引入,难于辐射交联的EVOH在较低的辐射剂量下就可以辐射交联,具备成为强化交联剂的可能。通过研究改性EVOH与聚乳酸共混物的辐射效应,发现聚乳酸进入交联网格,证明改性EVOH具有一定的强化辐射交联剂的作用。Ethylene-vinyl alcohol-acrylic（EVOH-AA） graft material was prepared by esterification.Fourier transform infrared spectrum（FT-IR） was used to characterize the graft product.Gel extraction results show that,EVOH which is difficult to cross-link can become easier to cross-link by radiation at a low absorbed dose due to introduction of vinyl double bond,with the possibility to be used as a kind of crosslinking agent.It is found that poly（lactic acid）（PLA） can enter the crosslinking network by studying the radiation effect of functionalized EVOH/PLA blends.It is demonstrated that functionalized EVOH has certain role of enhanced radiation crosslinking agent.
