Abstract

Abstract: Sequential poly(vinyl acetate)/polyi (methacrylate) interpenetrating polymer networks (PVAc/PMA-IPNs)were synthesized. By increasing crosslinking density of either component, the two glass transition temperatures corresponding to the individual component were merging into one, due to the increased forced compatibility. The effect of network I (PVAc) appeared more obvious. Comparison between experimental and theoretical values of modulus suggested the existence of a dual phase continuity. TEM photographs showed about 100Å domains.

Key words: IPN, Compatibility, Polyvinylacetate, Polymethacrylate, Morphology
