Synthesis of highly branched polystyrene via atom transfer radical polymerization with p-styrenesulfonyl chloride as an initiator

Highly branched polystyrene was prepared by atom transfer radical polymerization of styrene with p-styrenesulfonyl chloride as an initiator. The molecular weights and molecular weight distributions of the polymers obtained at different ratios of the initiator to the monomer and different monomer conversions were determined by gel permeation chromatography. It was found that the molecular weights were higher than the calculated ones by assuming that one polymer chain was generated per p -styrenesulfonyl chloride molecule, and that the molecular weight distributions were broad with multi-peaks.
