When a solution containing both styrene -butadiene block copolymer ( SBS ) and methyl methacrylate is treated with an initiator both homopolymerization of the methyl methacrylate and graft copolymerization of the methyl methacrylate onto the SBS occur. The amount of graft copolymerization depends up
Copolymerizations of methyl methacrylate with the Li, Na and K salts of methacrylic acid have been studied in methanol solution at 60 Β° . Reactivity ratios have been calculated by the methods due to Mayo and Lewis, Fineman and Ross and Peckham. The rate of copolymerization decreases as the size of t
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
