Control of Molecular Weights and Polydispersities in Radical Polymerization of Styrene in the Presence of Stable Radicals.

摘要

Radical polymerization of styrene was investigated by initiation with benzoyl peroxide and AIBN, in the presence of nitroxy-based stable radical scavengers. The effects of the concentration of the nature and concentration of nitroxy radicals and the nature and concentration of the radical initiators on the kinetics, evolution of molecular weights and polydispersities of polystyrenes prepared at various temperatures are also discussed.
