摘要	The linear benzyl chlorine-free poly(4-acetoxystyrene) (PSTO) with low polydispersity (M-w/M-n = 1.3) is obtained through anisole quenching of the living polymerization of 4-acetoxystyrene initiated with the St-Cl/SnCl4/n-Bu4NBr system in CH2Cl2. The alkylation reaction rate increases with increasing anisole concentration and temperature. With a 4-fold excess of anisole over the initiator, end-chlorine groups are completely capped by anisole in 30 minutes at -15 degrees C through adding extra SnCl4 prior to the alkylation reaction. In addition, by using 2-methylanisole and 2,6-dimethylanisole as capping agents, it is verified that both para- and ortho-positions substitution of living PSTO cations to the anisole occur during alkylation reactions.
