Independent Claim 81 words
A curable composition which comprises: (A) an oxypropylene polymer which contains, in its main polymer chain, a repeating unit of the formula and which has at least one silicon atom-containing group with a hydroxyl group or a hydrolyzable group being bound to the silicon atom and has an Mw/Mn ratio of not more than 1.6 and a number average molecular weight of not less than 6,000, (B) an organic carboxylic acid salt of divalent tin, and (C) an organic amine compound.
Claim 2
Dependent Claim 22 words
A curable composition as claimed in Claim 1, wherein the component (A) polymer has an Mw/Mn ratio of not more than 1.5.
Claim 3
Dependent Claim 25 words
A curable composition as claimed in Claim 1 or 2, wherein the component (A) polymer has a number average molecular weight of 6,000 to 30,000.
Claim 4
Dependent Claim 25 words
A curable composition as claimed in any of Claims 1 to 3, wherein the silicon atom-containing group occurs at the terminal of the molecular chain.
