[PROBLEMS] To provide a polyoxyalkylene polymer (hereinafter, referred to as POAP) curable composition having low viscosity, excellent handleability, and capable of adjusting curability and elongation characteristics of a cured product in a wide range. . Kind Code: A1 A hydrolyzable silicon-group-containing POAP (A) in which two hydrolyzable groups are bonded to Si, and a hydroxyl-group-containing POAP. After introducing an unsaturated group into the terminal of the AP, a hydrolyzable silicon group-containing POAP (B) obtained by reacting an SH group-containing compound with a hydrolyzable silicon group having three hydrolyzable groups bonded to Si is contained. |
