摘要: 以乙烯-醋酸乙烯酯共聚物(EVA)为原料,通过控制VA的水解程度制得一系列不同组成的乙烯-醋酸乙烯酯-乙烯醇三元共聚物.研究表明:随水解程度的增加共聚物的结晶性越来越好.在一定水解度范围内共聚物具有良好的综合力学性能,是一种新型的热塑性弹性体.

关键词: 乙烯-醋酸乙烯酯-乙烯醇三元共聚物, 结晶度, DSC, 力学性能

Abstract: A series of ethylene-vinyl alcohol-vinyl acetate terpolymers were produced by controlling the degree of hydrolysis of ethylene-vinyl acetate (EVA)copolymer. The results of DSC and mechanical property studies indicate that the crystallinity of the terpolymers increases with increasing the degree of hydrolysis. The terpolymers within a certain range of degree of hydrolysis have fine comprehensive mechanical properties and they can be used as a new type of thermoplastic elastomer. The correlation between the structure of terpolymers and mechanical properties has been explored.

Key words: Ethylene-vinyl alcohol-vinyl acetate terpolymers(EVA), Crystallinity, Thermal analysis, Mechanical property
