Substantial modifications of ethylene/vinyl acetate copolymers: Saponification and graft copolymerization

Abstract: Modifications of ethylenehinyl acetate copolymers (EVA) by saponification and graft polymerization with various acids were studied. The greater the degree of saponification, the higher is the melting temperature, the crystallinity and the melt viscosity of poly(ethy1ene-co-vinyl alcohol-co-vinylacetate). Tensile tests display that the flexibility of EVA decreases gradually as the degree of saponification increases. This effect may be caused by the interaction of hydrogen bridges after saponification. Graft cop… Show more
