PROCESS FOR PRODUCING VINYL POLYMER HAVING FUNCTIONAL GROUP AT END AND VINYL POLYMER HAVING FUNCTIONAL GROUP AT END

摘要

A process for producing a vinyl polymer having a functional group at an end which comprises a step in which a vinyl monomer is polymerized by radical polymerization in the presence of a halogen compound to synthesize a vinyl polymer having a halogen atom at an end and a step in which the terminal halogen atom of the vinyl polymer is replaced with a group having a function al group to incorporate the functional group into the end, wherein the halogen compound has a structure which comprises an aromatic ring, a carbon atom bonded to the ring, and the halogen atom bonded to the carbon atom and the radical polymerization is conducted by irradiation with light optionally in the presence of a compound of a metal in Groups 14 to 16 or by heating in th e presence of a compound of a metal in Groups 14 to 16; and a polymer produced by the process.
