POLYMER AND CURABLE COMPOSITIONS IMPROVED IN STORAGE STABILITY

摘要

Current compositions which comprise vinyl polymers having crosslinking silyl groups often suffer from retarded curing after the storage. A curable composition comprising as the essential component a vinyl polymer (I) which has at least one crosslinking silyl group at the end and comprises essential constituent units derived from a monomer having a methyl ester group; sealing compounds, liquid gaskets, and adhesives, made by using the curable composition; a polymer which has at least one crosslinking functional group at the end and a backbone chain made of a vinyl polymer, characterized in that methyl acrylate accounts for 2 to 80 wt% of the monomers constituting the backbone chain; and curable compositions improved in storage stability, which comprise as the essential components the following two components: (a) a vinyl polymer having at least one crosslinking silyl group and (b) a compound having a methyl ester group except the polymer (a).
