摘要：

Thermal and microwave-induced free-radical non-aqueous dispersion polymerization of methyl methacrylate (MMA) in the presence of poly(styrene)-block-poly(ethene-alt-propene) dispersing agent were compared. For controlled polymerization in the microwave field, a new microwave polymerization reactor was built to afford uniform heating and to control temperature via microwave power variation. Al identical MMA concentration and polymerization temperature of 70 degrees C no special effect of the microwave field on conversions, molecular weights and particle sizes of PMMA was detected with respect to conventional thermal free radical dispersion polymerization.
