摘要：

A series of poly(styrene-b-ethylene oxide) copolymers were investigated as stabilizers for the dispersion polymerization of styrene in methanol. The effects of stabilizer molecular weight, stabilizer/anchor ratio and stabilizer concentration on particle diameter and polydispersity were examined. Large (2 mu m) monodisperse polystyrene particles were formed when a low molecular weight stabilizer was used, while broad bimodal distributions were found for polystyrene particles stabilized by higher molecular weight copolymeric stabilizers.
