PROBLEM TO BE SOLVED: To provide a cured product exhibiting excellent strength and elongation while maintaining workability of an organic polymer composition having a reactive silicone group. SOLUTION: Provided is the composition comprising an organic polymer (A) having groups represented by general formula (1):-[Si(R<SP>1</SP><SB>2-b</SB>)(X<SP>1</SP><SB>b</SB>)O]<SB>m</SB>Si(R<SP>1</SP><SB>3-a</SB>)X<SP>1</SP><SB>a</SB>(1) and an acid (B). Therein, R<SP>1</SP>is a 1 to 20C alkyl group, a 6 to 20C aryl group, a 7 to 20C aralkyl group, or a triorganosiloxy group represented by formula: (R')<SB>3</SB>SiO-, wherein two or more R<SP>1</SP>groups exist, the R<SP>1</SP>groups may be identical or different from each other; R' is a 1 to 20C monovalent hydrocarbon group, where the three R's may be identical or different from each other; X<SP>1</SP>is OH or a hydrolysable group; (a) and (b) are each 0 or 1; m(b)s may be identical or different from each other, and satisfy a+Σb=1; and (m) is an integer of 0 to 19.
