Studies on the Property of Ethylene-vinyl Alcohol-vinyl Acetate Terpolymers

Abstract

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
