摘要:
Living polymerization of styrene was obtained in the system 1-phenylethyl chloride/TiCl4/Bu2O in mixture of 1,2-dichloroethane and n-hexane (55:45 v/v) at -15 degreesC. The number-average molecular weights (M-n) of the polymers obtained increased in direct proportion to the monomer conversion and agreed well with the calculated values. The first-order kinetic plots were linear. The molecular weight distributions were narrow (M-w/M-n=1.46-1.56).
