Polymerization of a monomer overcome many of the disadvantages of the bulk process. The solvent acts as diluent (fisolvent also allows easier stirring, since the viscosity of the reaction mixture is decreased. Thermal control is much easier insolution polymerization compared to bulk polymerization. On theother hand, the presence of solvent may present new difficultiesunless the solvent is chosen with appropriate consideration, chaintransfer to solvent can be a problem. Further, the purity of thepolymer may be affected if there are difficulties in removal of thesolvent. Vinyl acetate, acrylonitrile, and the esters of acrylic acidare polymerized in solution. Ethylene polymerization is sometimesa solution process, since water or benzene may be added to aid inthe problem of heat control.
