CURABLE COMPOSITION

摘要

An odorless curable composition containing a hydrolyzable silyl group-containing urethane compound with good storage stability is provided. A curable composition comprising 100 parts by mass of a polymer (P) obtained by a urethane-forming reaction of a polymer (pP) having a polyoxyalkylene chain and hydroxyl groups and a compound (U) represented by the following formula (I): Si(X1)m(R1)3-m-Q-NCO   (I) (wherein Q is a C2-20 bivalent linear hydrocarbon group, X1 is a C1-6 alkoxy group, R1 is a C1-6 alkyl group, and m is an integer of from 1 to 3) in the presence of a urethane-forming catalyst and from 0.0001 to 0.1 part by mass of an inorganic acid or an organic acid having an active hydrogen bonded to an oxygen atom.
