(57) Abstract: A vinyl polymer having an alkenyl group or a crosslinkable silyl group at a main chain terminal, a method for producing the polymer, and A curable composition using the polymer is provided. SOLUTION: A vinyl polymer having a halogen at at least one terminal of a main chain is produced, By substituting with an alkenyl group-containing oxyanion, a vinyl polymer having an alkenyl group at at least one terminal of the main chain is produced. Further, by adding a hydrosilane compound having a crosslinkable silyl group to this polymer, a vinyl polymer having a crosslinkable silyl group at at least one main chain terminal is produced. |
