Abstract
Abstract Vinyl acetate and citraconic anhydride are known to give 1:1 radical alternating copolymers regardless of the monomer feed composition. The mechanism of this copolymerization involves free monomers and a charge-transfer complex between them. We undertook a study of the microstructure by NMR and thermogravimetric analysis (study of the thermal cis elimination of acetic acid). We determined a quantitative correlation between the theoretical proportion of D-A diads obtained in the reaction corresponding to the addition of the complex between comonomers on the growing chain and the microstructure of the copolymers determined by thermogravimetric analysis.
