## Abstract The bulk copolymerizations of acrylonitrile (AN) with vinyl acetate (VAc) initiated by azobisisobutyronitrile (AIBN) and the suspension copolymerization of AN with VAc and sodium methallylsulfonate (SMAS) in water with a Na~2~S~2~O~5~βNa~2~ClO~3~ redox initiator system at 65Β°C, were inv
Graft copolymers of acrylonitrilc, methyl metliacrylate and vinyl acetate on blcached holocellulose were obtained by the use of ceric ions. The ceric ion concentration, a t which maximum graft levels were attained, depends on the type of monomer. The dependence of the extent of graft copolytncr form
