Curable polyether composition.

摘要

A novel curable composition is provided, including: (A) an oxypropylene polymer containing a main polymer chain having a repeating unit represented by the general formula (1): <CHEM> and at least one reactive silicon group containing a silicon atom to which a hydroxyl group or hydrolyzable group is bonded, said oxypropylene polymer having Mw/Mn of 1.6 or less and a number-average molecular weight of 6,000 or more; and (B) a compound represented by the general formula: <CHEM> wherein Q represents a C1-20 monovalent hydrocarbon group; and Z represents a C1-20 monovalent hydrocarbon group or an organic group internally containing a functional group capable of forming a coordinate bond to Sn as a curing catalyst in an amount of 0.01 to 10 parts by weight based on 100 parts by weight of said oxypropylene polymer.
