The copolymerization of methyl methacrylate and styrene, in the presence of zinc chloride, was conducted in the aqueous phase. The zinc chloride acting as a complexing agent.Among the factors affecting the polymerization yield, we have; the level of complexing agents, the monomer ratio and the temperature.The polymers were characterized for their molecular weight (G.P.C.) and analyzed by N.M.R. and D.T.A.A model taking into account the various parameters is proposed.

“…A proper choice of reaction conditions and solvent was necessary for this synthesis. Literature (Gaylor and Takahashi 1969;Funt et al 1970;Funt and Rybicky 1971) cite the usefulness of donor-acceptor complex arising from a combination between zinc salts and monomer in initiating the polymerization. Since supporting electrolytes were highly ionic in character, the solvents with high dielectric constant DMSO and DMF were used.…”

Electroinitiated polymerization of urethane was carried out using electrolysis of MDI (methylene 4,4'-diphenyl diisocyanate) with polyoxypropylene glycol in dimethyl sulphoxide (DMSO) and dimethylformamide (DMF) in the presence of oxides and chlorides of Zn, Cd, Pb and Sn as supporting electrolytes. These salts also served as complexing agents. The polymer formation took place only in the cathodic compartment having good yields with highest Rp of 16"25% per h and polymerization efficiency of 30 x 102 moles of monomer converted per Faraday in DMF solvent. The mechanism of polymerization has been suggested.

“…Although the bulk of this charge-transfer electroinitiated polymerization work has been related to copolymerization reactions,14 some studies have been done on metal salt-catalyzed homopolymerizations. [5][6][7] In this instance the donor-acceptor is composed of the same monomeric species, and electroinitiation requires electron transfer between metal salt complexed and uncomplexed monomers.…”

SynopsisThe electroinitiated polymerizations of styrene, 2-vinylnaphthalene, and 9-vinylanthracene were compared in sulfolane and acetone solvents in the presence of ZnCl2. The relative orders of polymerization rates and polymerization efficiencies, in both solvents, were 9-vinylanthracene > P-vinylnaphthalene > styrene, with faster rates and higher efficiencies occurring in sulfolane. Data obtained from viscosity and gel permeation chromatography (GPC) studies indicate that the molecular weights of the polymers produced in these systems are extremely low, <5000. Chemical composition and infrared (IR) spectral data suggest that abnormal transfer reactions (possibly from solvent) may be occurring in the electroinitiated 9-vinylanthracene polymerizations. The polymerization mechanism appears to be cationic in these monomer-solvent systems with ZnCl2.
