Summary: The telomerization of 10‐undecenol with alkyl hydrogenphosphonate was studied in order to synthesize telomers of different molecular weights. The study showed that telomers from 10‐undecenol could be obtained despite the fact that the double bond has a low reactivity. The kinetic constant Kp2/KTe was determined to be 7 × 10−4 l · mol−1 · s−1 at 135 °C and the transfer constant CT was 0.057. These values are normal for a low activity telogen such as hydrogenphosphonate and for slightly reactive monomers like 10‐undecenol.SEC chromatogram of telomers obtained in the reaction of 10‐undecenol addition.imageSEC chromatogram of telomers obtained in the reaction of 10‐undecenol addition.

SynopsisA new formula for redox catalyzed telomerization kinetics was set up: Im,, = C M~ (Me)/(M) + Cxy (XY)/(M), where C M~ is the transfer constant for the metallic ion Me, Cxy is the transfer constant for the telogen XY, M the monomer, and m, 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 (Chle) is the predominant factor influencing telomer molecular weight. This formula was verified by telomerizations of three monomers [chlorotrifluoroethylene (CTFE), acrylic acid, and ethyl acrylate] with CC4, catalyzed with ferric chloride-benzoin. In this last case the initiation rate constant (mi), the initiation and termination rates, and the radical concentration were measured.
