14 C]-Azoisobutyronitrile was used to initiate free radical polymerization of methacrylonitriIe at 60Β° in dimethylsulphoxide solution. Approximately two initiator fragments were found combined with each polymer molecule, indicating that termination was almost exclusively by combination of pairs of

Desorption of free radicals from particles can cause an emulsion polymerization system to deviate from Smith-Ewart case I1 kinetics. A mechanistic model has been developed to predict the effect of desorption of radicals from particles on the kinetics of semibatch emulsion polymerization of methyl ac
Al~tract---Methyl a-p-chlorobenzylacrylate and methyl :t-p-methoxybenzylacrylate were synthesized from dimethylmalonate by well known organic reactions. Both monomers were polymerizcd by a free-radical mechanism in benzene and their ceiling temperaturc determined. Comparison of the ceiling temperatu
