Monomer Reactivity Ratios in Vinyl acetate -Diisobutyl Fumarate Copolymerization

摘要

Studies on Polymerization of fumarates have been reported results show that their homopolymerization and copolymerizationa are often difficult, in particular for n-alkyl fumarate. However their copolymerizations with other Vinyl monomers are reportedly carried out. In this work, a series of copolymerization of Diisobutyl fumarate(DiBF) with Vinyl acetate(VAc) were carried out, at 70°C with AIBN as initiator. Reaction was topped before 10% conversion, copolymer compositions were analyzed by elementary analysis and ~1HNMR. Results are given in Table 1.
