PROBLEM TO BE SOLVED: To provide a crosslinkable siloxane-urea copolymer, to provide a method for producing the same, to provide use thereof, to provide crosslinkable composition containing the copolymer and vulcanizate thereof, to provide a method for producing the vulcanizate, and to provide use thereof. SOLUTION: The copolymer is represented by formula (I): (A)<SB>a</SB>(B)<SB>b</SB>(C)<SB>c</SB>(I). The crosslinkable composition contains at least one of the copolymers. The vulcanizate is obtained by valcanizing the composition. Wherein (A), (B), (C), a, b, c represent specific items. The organopolysiloxane-polyurea-block copolymer has good thermoplastic processability and can adjust the content of moisture-crosslinking groups, wherein polymer chain length is unrelated.
