Two kinds of polymethylene-based macromonomers were prepared by living polymerization of ylides. One macromonomer PM-methacrylate was obtained by the transformations of hydroxyl group at the chain end of polymethylene obtained by living polymerization of ylides. The other macromonomer PM-styryl was synthesized via living polymerization of ylides which initiated by organoborane which was prepared by hydroboration of divinylbenzene, and after the oxidation by trimethylamine-N-oxide dehydrate (TAO), α-p-vinylphenyl-ω-hydroxypolymethylene were obtained. The chain structure, molecular weight and its distribution of the two macromonomers were investigated by high temperature 1H NMR spectra, FT-IR and high temperature GPC.

Key words: living polymerization of ylides, functionalization of polyolefin, macromonomer
