Patent ID: 7202310

Claim:
A vinyl polymer having a crosslinkable silyl group at at least one terminus of its main chain, which is prepared by adding a hydrosilane compound having a crosslinkable silyl group to a vinyl polymer having an alkenyl group of the following general formula (1) at at least one terminus of its main chain: —CH 2 —C(R 1 )(R 2 )—O—R 3 —C(R 4 )═CH 2 (1) wherein R 1 and R 2 are the same or different, and each represents a hydrogen atom or a univalent organic group derived from the group bound to a vinyl group of a vinyl monomer used for the production of a main chain of the polymer; R 3 represents a divalent organic group having 1 to 20 carbon atoms and optionally containing one or more ether or ester bonds; R 4 represents hydrogen, an alkyl group having 1 to 10 carbon atoms, an aryl group having 6 to 10 carbon atoms, or an aralkyl group having 7 to 10 carbon atoms.
