摘要：

Poly(methyl methacrylate) (PMMA) dispersions in decane stabilized by polystyrene-block-poly(ethylene-co-propylene) copolymer copolymer were prepared with various monomer and steric stabilizer concentrations. The number of PMMA macromolecules formed in the dispersion polymerization does not depend on monomer and stabilizer concentrations. The kinetics of polymerization seems to be only slightly affected by the colloidal character of the system. Correlations have been established between the parameters of the whole system, of dispersion particles and of the individual PMMA macromolecules.
