Abstract:
1. A process for preparing a vinyl polymer having a silanol group at one or more termini thereof, which comprises: (1) synthesizing a vinyl polymer by living radical polymerization, (2) subjecting a compound having at least two low-polymerizable alkenyl groups to reaction as a second monomer at the final stage of said polymerization or after completion of the reaction involving a predetermined monomer(s) to thereby sythesize a vinyl polymer having an alkenyl group at one or more one termini thereof, (3) carrying out the hydrosilylation reaction of said vinyl polymer having an alkenyl group at one or more one termini thereof with a silicon compound having both a silicon atom-bound hydrolyzable group and a hydrosilyl group, and (4) converting said hydrolyzable group to a silanol group by hydrolysis.
