Abstract
We present a study of the dispersion polymerization of methyl methacrylate in supercritical carbon dioxide in the presence of poly(dimethylsiloxane)-mono-methyl acrylate. The heterogeneous polymerization is followed in situ by turbidity at a pressure 330 bar and a temperature of 60°C. The turbidity spectra of the system are measured directly in the autoclave to give the average-number of particles per unit volume N av /V and the average-diameter σ τ increases steadily during this period. A comparison of the rate of polymerization thus obtained with kinetic data measured in bulk, suggests that the formation of particles proceeds through coagulation of the polymer which is formed in the homogeneous phase.
