PROBLEM TO BE SOLVED: To provide a room temperature curable composition comprising a hydrolyzable silicon group-containing oxyalkylene polymer, having a fast curing speed and sufficient pot life, and also having good mechanical properties after curing. An oxyalkylene polymer having a main chain substantially composed of a polyoxyalkylene chain and having a hydrolyzable silicon group at least at a part of a molecular end, wherein the hydrolyzable silicon group is represented by the following formula 1: -Si (OR) 3 ... Formula 1 (In Formula 1, R represents an organic group having 1 to 6 carbon atoms.) Or a mixture of oxyalkylene polymers having different groups as the hydrolyzable silicon groups is prepared at room temperature. To prepare. [Selection figure] None |
