Abstract
AbstractThe polymerization of certain vinyl monomers in the presence of some vinyl polymers leads to the formation of a chemical bond between the resulting two polymers. A study of the efficiency of this graft copolymerization process under various conditions in emulsion has been made and the following conclusions drawn. An increase in the catalyst concentration and temperature of polymerization increases the efficiency, while the addition of dodecyl mercaptan decreases it. The list of the monomers used in the order of decreasing activity toward graft copolymerization is vinyl chloride, vinyl acetate,and styrene. A list of polymers in order of decreasing susceptibility to graft copolymerization is polyvinyl chloride, polyacrylonitrile, polyvinyl a cetate, and polystyrene.
