Abstract

Reversible addition–fragmentation chain-transfer radical copolymerization of ethylene with vinyl acetate in the presence of azobis(isobutyronitrile) and xanthate as a chain-transfer agent was studied. Products containing 12–42 mol % vinyl acetate units were prepared under varied reaction conditions. The glass transition points and degradation temperatures of the polymers were determined. The rheological properties of ethylene–vinyl acetate copolymers were studied in detail. The effect of additions of the copolymers synthesized on the rheological characteristics of diesel fuel was evaluated. The ethylene–vinyl acetate copolymers synthesized reduce the limiting filterability temperature of the diesel fuel.
