POLYMER, PROCESSES FOR PRODUCING POLYMER, AND COMPOSITION

摘要

A vinyl polymer having a silanol, hydrolyzable silyl, or functional acrylic group at an end; a process for producing a vinyl polymer having a hydrolyzable silyl group at an end, which comprises reacting a vinyl polymer having a silanol group at an end with a silicon compound having two or more hydrolyzable groups; and a process for producing a vinyl polymer having a functional acrylic group at an end, which comprises reacting a vinyl polymer having a silanol group at an end with a silicon compound represented by the following general formula: XSiR2-G-O-C(O)C(L)=CH2 wherein X is a hydrolyzable group.
