CURABLE COMPOSITION IMPROVED IN PROPERTY AND CURABILITY, AND POLYMER

摘要

PROBLEM TO BE SOLVED: To solve a problem for a curable composition containing a crosslinkable silyl group that it often causes curing retardation after storage and to improve strength and elongation of the cured product. SOLUTION: The curing composition comprises as an essential ingredient a vinyl polymer having at least one crosslinkable silyl group at the end and comprising as an essential constituting unit a monomer bearing a methyl ester group. The polymer has at least one crosslinkable functional group at the end and the main chain thereof is composed of the vinyl polymer where methyl acrylate accounts for 2-80% by weight or methyl methacrylate accounts for 2-50% by weight in the monomers constituting the main chain.
