The contributions of Prof. Kenneth F. O'Driscoll to radical copolymerization kinetics

Twenty low-conversion statistical copolymers of styrene and 2-methoxyethyl methacrylate with various composition were prepared. The dependence of the copolymer composition, molecular weight, initiation efficiency and other parameters on the composition of the monomer mixture is discussed. Kinetic data are correlated by means of various models of the copolymerization kinetics. The best fit with experimental data is provided by a diffusion-controlled termination model, especially its dyad variant suggested in this study.

Copolymerization Kinetics

The free radical copolymerization kinetics of polyethylenglycol allylether (APEG) with acrylic acid (AA) had been studied in aqueous solution through using ammonium persulfate (APS) and 30% hydrogen peroxide (H2O2) as initiators. The structure of polycarboxylate superplasticizer had been characterized by IR and 1H-NMR. The rate of copolymerization was proportional to the molar ratio of monomers (AA:APEG) to the power of 0.4405, and to the amount of initiator (1.5%APS-2%H2O2, mass ratio to monomers) to the power of 0.7819, respectively. The overall observed activation energy of copolymerization was 45.048 kJ/mol. The kinetic relationship of copolymerization reaction of APEG with AA had been established as follow: Rp∝[APEG/AA]0.4405[APS-30%H2O2]0.7819e-5418/T. The temperature and initiator were main influencing factors on polymerization reaction.
