Ks. Murthy et al., POLY(STYRENE DISULFIDE) AND POLY(STYRENE TETRASULFIDE) AS CHAIN TRANSFER AGENTS IN THE RADICAL POLYMERIZATION OF STYRENE, Polymer, 37(24), 1996, pp. 5541-5543
This is a first report on the chain transfer behaviour of polysulfide
polymers, namely poly(styrene disulfide) (PSD) and poly(styrene tetras
ulfide) (PST), in the radical polymerization of styrene. It was observ
ed that while PSD acts as a conventional chain transfer agent, PST act
s as a retardant. Comparison of the chain transfer constants of PSD an
d PST with that of the corresponding simple sulfides indicates that po
lysulfide polymers are better chain transfer agents. Copyright (C) 199
