摘要：

Two halogenated compounds, ICFCICF2Cl et BrCF2CFCl-Br, were synthesized and characterized and were further used as chain transfer agents (CTAs) for the radical polymerization of vinyl phosphonic acid (VPA). only BrCF2CFCl-Br was efficient CTA towards VPA as the chain transfer constant C-T value of I was evaluated. This value clearly demonstrates that the chain-end of each VPA polymeric chain is BrCF2CFCl group, which will allow to perforin a dehalogenation from this group, leading to a new VPA macromonomer. Hence, VPA telomers were synthesized with Mn values ranging from 1800 to 6700 g/mol.
