The invention relates to a method for preparing a vinyl ether polymer by photo-initiated polymerization, which comprises the step of: under a protective atmosphere, performing photo-initiated polymerization on a vinyl ether monomer in the presence of an organic halogenated hydrocarbon and manganese carbonyl under irradiation of light having a wavelength of 365-550 nm at −25° C. to 25° C., to obtain a vinyl ether polymer after the reaction is completed. In the method, a vinyl ether monomer is subjected to cationic polymerization in the presence of manganese carbonyl and an organic halogenated hydrocarbon under visible light, to prepare a vinyl ether polymer with controlled molecular weight and narrow molecular weight distribution.

Disclosed herein are a modified high cis polydiene polymer, processes for preparing the modified high cis polydiene polymer, and tire rubber compositions containing the modified high cis polydiene polymer.

Novel functionalized rubbers having low hysteresis and good compatibility with fillers, such as carbon black and silica, have been synthesized. These functionalized rubbers, including functionalized polybutadiene rubber and functionalized styrene-butadiene rubber, can be beneficially used in making a wide variety of rubber products that have enhanced physical properties. These improved properties are realized because the functional groups therein improve compatibility with reinforcing fillers that are typically included in such rubber compounds. These functionalized rubbers are comprised of polymer chains of the structural formula:
