Abstract

The work presents the results of determination of reactivity ratios for vinyl/divinyl systems based on dodecyl methacrylate and four oxyethylene glycol dimethacrylates. Various methods (based on terminal model and penultimate effect) were used for calculation of experimental results. The experimental data were obtained by gas chromatography (determination of unreacted monomers in the feed) and by NMR analysis of the soluble copolymer. It was found that dimethacrylates were preferentially built into the copolymer chain. These results were in good agreement with quantum-mechanical calculations based on the analysis of heats of formation of short-chain oligomers. Key words: copolymerization, dimethacrylates, monomethacrylates, reacti-vity ratios, terminal model, penultimate effect, quantum-mechanical calcula-tions.
