Title:
MANUFACTURING METHOD FOR POLYMER COMPRISING HYDROLYZABLE SILYL GROUP, AND POLYMER, CURABLE COMPOSITION, AND CURED PRODUCT
Document Type and Number:
WIPO Patent Application WO/2022/181545
Kind Code:
A1
Abstract:
According to the present invention, a polymer comprising a hydrolyzable silyl group is manufactured by causing a silane compound comprising a hydrolyzable group or a hydroxyl group and a vinyl group on a silicon atom to undergo a metathesis reaction with a polymer comprising a vinyl group in the presence of a catalyst. Among the hydrolyzable silyl groups comprised by the polymer, 80 mol% or more have a structure represented by the formula: -CH=CH-Si(R1)3-a(X)a. In the formula, R1 represents a substituted or unsubstituted 1-20C hydrocarbon group; X represents a hydroxyl group or a hydrolyzable group; and a represents 1, 2, or 3.
