Solvent Effect on Radical Graft Polymerization onto 1, 4-Polybutadiene

Abstract

Radical graft polymerizations of styrene and methyl methacrylate onto 1, 4-polybutadiene were carried out in various solvents using α, α'-azobisisobutyronitrile as an initiator. Maxi-mum vaValues of grafting and grafting efficiency were observed in the solvent whose dielectric constant was similar to that of monomer.
