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.

Copolymerization Kinetics

Kinetic modeling of the bulk free radical copolymerizations of n-butyl acrylate (BA) and 2-ethylhexyl acrylate (EHA); methyl methacrylate (MMA) and EHA; as well as BA, MMA and EHA was performed using the software PREDICI®. Predicted results of conversion versus time, composition versus conversion, and molecular weight development are compared against experimental data at different feed compositions. Diffusion-controlled effects and backbiting for BA were incorporated into the model as they proved to be significant in these polymerizations. The set of estimated global parameters allows one to assess the performance of these copolymerization systems over a wide range of monomer compositions.
