【摘要】：乙烯-乙酸乙烯酯共聚物(EVA)以其优异的耐低温性、耐氧化性、耐环境应力开裂性和耐腐蚀性等性能,在很多领域得到了广泛应用。近年来,为了赋予其新的性能和功能,拓展其应用领域,对EVA的接枝改性及其应用研究受到广泛关注。文章首先介绍了利用熔融接枝法、溶液接枝法以及乳液接枝法合成EVA接枝聚合物的研究新进展,接着以EVA接枝马来酸酐聚合物为例分析了接枝反应机理,然后对EVA接枝聚合物的表征方法包括仪器法和化学滴定法及应用进行总结和评述。最后对EVA接枝聚合物的合成方法的优缺点、表征方法及其应用的发展前景进行了阐述,指出溶液接枝法是未来的发展趋势,共混相容剂、膜材料和原油降凝材料是其未来比较广泛的应用领域。
[Abstract]:Ethylene-vinyl acetate copolymer (EVA) has been widely used in many fields due to its excellent low temperature resistance, oxidation resistance, environmental stress cracking resistance and corrosion resistance. In recent years, in order to endow the EVA with new properties and functions and expand its application fields, the grafting modification of EVA and its application have been paid more and more attention. In this paper, the recent progress in the synthesis of EVA grafted polymers by melt grafting, solution grafting and emulsion grafting is introduced. Then the graft mechanism of EVA grafted maleic anhydride polymer is analyzed. Then the characterization methods of EVA grafted polymers including instrumental method and chemical titration method and their applications are summarized and reviewed. In the end, the advantages and disadvantages of the synthesis method of EVA grafted polymer, the characterization method and the development prospect of its application are described. It is pointed out that the solution grafting method is the development trend in the future, and the blend compatibilizer. Membrane materials and crude oil anticoagulant materials are widely used in the future.
