A new formula for redox catalyzed telomerization kinetics was set up: 1/D bar P bar//n equals C//M//e(Me)/(M) plus C//X//Y(XY)/(M), where C//M//e is the transfer constant for the metallic ion Me, C//X//Y is the transfer constant for the telogen XY, M the monomer, and D bar P bar//n is the degree of polymerization. This study has shown that classic transfer and termination reactions can be neglected because of their slow rates and that the metal transfer constant (C//M//e) is the predominant factor influencing telomer molecular weight. This formula was verified by telomerizations of three monomers left bracket chlorotrifluoroethylene (CTFE), acrylic acid, and ethyl acrylate right bracket with CCl//4, catalyzed with ferric chloride-benzoin. In this last case the initiation rate constant (fK//i), the initiation and termination rates, and the radical concentration were measured.
