接枝物EVA-g-PBMA的合成及表征

Preparation and characterization of grafted polymer EVA-g-PBMA

本文合成了具有端羟基的聚甲基丙烯酸丁酯(PBMA OH),并通过与MA反应,实现了端羟基转化,为接枝EVA水解产物起到了“搭桥”的作用。通过H1NMR对不同水解度的EVA皂化产物进行了序列结构剖析,并合成了新型接枝物EVA g PBMA。

Hydroxyl-terminated PBMA was synthesized successfully by adding chain transfer agents of mercaptoethanol(TEG).In order to be grafted on EVA-OH,carboxyl-terminated PBMA was prepared by reacting the hydroxyl-terminated PBMA with maleic anhydride.The microstructures of the saponified EVA were studied by H^1NMR.The newly grafted polymer of EVA-g-PBMA was also synthesized and characterized by means of IR.
