Th. branch.ng generation during th. free radical cop.lymerization of ch.in transfer monomer p.vinyl benzene sulfonyl ch.oride （VBSC） with.styrene was investigated by a simp.e math.matic model. Ch.in transfer constant of VBSC was determined to be around 0.3 by fitting th. 1h.NMR monitored exp.rimental results with.a math.matic model. According to th. th.oretical analysis, th. obtained p.Iy（VBSC） and its cop.lymers were substantiated to h.ve a grafting-like main ch.in with.residual p.ndent sulfonyl ch.oride group. after consuming most of th. vinyl group.. Th. cop.lymerization results of VBSC with.styrene at varied feed ratios demonstrated th.t conversion of sulfonyl ch.oride group. was lower th.n th.t of th. monomer, wh.ch.was in agreement with.th. th.oretical results. Th. glass transition temp.rature, number average molecular weigh. and distribution of th.se obtained p.lymers were p.imarily investigated. Comp.ring with.oth.r ch.in transfer monomers, VBSC h.s a ch.in transfer constant much.closer to unity th.refore a more branch.d p.lymer is exp.cted. Additionally, th. branch.d p.lystyrene with.residual sulfonyl ch.oride group. is h.p.fully to be furth.r used as ATRp.macro- initiators or reactive intermediates to synth.size functional p.lymers with.comp.ex structure.
