Abstract
Living"/controlled radical polymerization of styrene initiated by benzyl chloride has been achieved by atom transfer radical polymerization (ATRP) catalyzed by iron dichloride tetrahydrate-triphenyl phosphine complexes at 120 C. When n(Fe) to n(P) is 1: 3, the polymer number-average molecular weight (M̄n) increases linearly with monomer conversion. If n(Fe) to n(P) is 1: 2 or 1: 4, the linear relation of M̄n to conversion does not exist, indicating that there exist many active centers in the polymerization.
