“…At these concentrations of the initial compounds the polymerizations proceed almost at the same rate from the beginning of the reaction till high conversions. The influence of PCC (which forms a copolymer in the reaction with the acrylic monomers 14 ) on the kinetics is probably due to the familiar change in the copolymerization rate compared with simple homopolymerization, since, in the former case, radicals with a large difference in activity appear.…”

The polymerization of methyl methacrylate and butyl acrylate initiated by azo-bis-isobutyronitrile in the presence of metal-containing monomers (p-methylstyrene-, stilbene-and α-methylstyrenechromiumtricarbonyl) was studied. Kinetic parameters (i.e. the decrease in the autoacceleration during the polymerization of acrylic monomers, its shift towards a high conversion region in the presence of α-methylstyrenechromiumtricarbonyl, a linear dependence of the molecular weight of a polymethyl methacrylate and the shift of molecular-weight distribution curves to a high molecular weight region with conversion) demonstrate the influence of vinylarenetricarbonyl complexes of chromium on basic steps of polymerization. It is important to note that the above organometallic compounds enable the controlled synthesis of polymers under temperature conditions (50-70 • C) corresponding to those of the industrial polymer production.
