To provide a room-temperature-curable composition which comprises an oxyalkylene polymer containing hydrolyzable silicon groups, which has ensured working time and curing rate required for operation, and which can provide a cured article having good tensile properties. A room-temperature-curable composition comprising a polymer (a1) and a curing catalyst (b), wherein the polymer (a1) is a linear oxyalkylene polymer having at least two hydrolyzable silicon groups of the formula (1), at different molecular terminals:
€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ-Si(OR) 3 €ƒ€ƒ€ƒ€ƒ€ƒ(1)
wherein each R independently represents a C 1-6 organic group. |
