Abstract:
1. A process for producing a vinyl polymer having a group represented by the following general formula (1) at a main chain terminus thereof: wherein, R 1 , R 2 and R 3 are the same or different and each represents a hydrogen atom, a monovalent hydrocarbon group containing 1 to 10 carbon atoms or a monovalent group containing 1 to 10 carbon atoms as derived from two hydrocarbon groups by being bound together via an ether bond or ester bond, and R 1 and R 2 or R 2 and R 3 may be combined together at respective other termini to form a cyclic structure, the process comprising carrying out polymerization of a vinyl monomer by the living radical polymerization technique, reacting, at the end point of the polymerization, the resulting polymer with a compound having both a reactive functional group and an ethylenically unsaturated group to give a vinyl polymer having a reactive functional group at a main chain terminus thereof, and reacting the reactive functional group of said vinyl polymer having the reactive functional group at a main chain terminus thereof with a compound represented by the following general formula (2): wherein, R 1 , R 2 and R 3 are defined as above, R 4 and R 5 are the same or different and each represents a hydrogen atom, a monovalent hydrocarbon group containing 1 to 10 carbon atoms or a monovalent group containing 1 to 10 carbon atoms as derived from two hydrocarbon groups by being bound together via an ether bond or ester bond and X represents a chlorine, bromine or iodine atom.
