Abstract
| - A comprehensive study is presented of aqueous heterophase polymerization of styrene withtwo kinds of reactive poly(ethylene glycol)s, each with an average molecular weight of the poly(ethyleneglycol) units of 400 g mol-1: symmetrical poly(ethylene glycol)-azo-initiators with either terminal hydroxylor styryl groups. Two kinds of stabilizers have been employed either sodium dodecyl sulfate orcetyltrimethylammonium bromide. Results are presented with regard to polymerization kinetics (reactioncalorimetry), average particle sizes (dynamic light scattering), molecular weights (size exclusionchromatography), particle morphologies (transmission electron microscopy), swelling ratios (in water andtetrahydrofuran), and cross-linking density (analytical ultracentrifugation). These results reveal theexciting possibilities of reactive poly(ethylene glycol)s in heterophase polymerization.
