PROBLEM TO BE SOLVED: To use a polymer having a hydrolyzable silicon group obtained from a silane compound which can be easily handled industrially as a raw material, to have low viscosity, excellent handling properties, adhesion and mechanical properties. Provided is a curable composition which is excellent in physical properties of a cured product after curing such as strength and weather resistance, and furthermore, can adjust a curing speed in a wide range. SOLUTION: An unsaturated group is introduced into a terminal of a polyoxyalkylene polymer (A) having a hydrolyzable silicon group in which two hydrolyzable groups are bonded to silicon and a polyoxyalkylene polymer having a hydroxyl group. Thereafter, a polyalkylene polymer (B) having a hydrolyzable silicon group obtained by reacting a compound having a mercapto group with a hydrolyzable silicon group having three hydrolyzable groups bonded to silicon, and a polymerizable polymer A room temperature curable composition (D) containing a polymer (C) obtained by polymerizing an unsaturated group-containing monomer (E) as an essential component is used. |
