摘要

A (poly) oxyalkylene block silyl ester copolymer comprising silyl ester copolymerblock units (A) and block units (B), the units (A) comprising (a) component units derivedfrom a polymerizable unsaturated carboxylic acid silyl ester, and (b) polymerizableunsaturated monomer units other than the component units (a), the units (B) derivedfrom a mercapto compound represented by the following formula (1) or (2), and furtheran antifouling paint comprising the (poly) oxyalkylene block silyl ester copolymer.[err]wherein R[err] represents a hydrocarbon group or ether-bond-containinghydrocarbon group having a valency of I or higher and having 1 to 30 carbon atoms; R[err]represents a bivalent hydrocarbon group having 1 to 30 carbon atoms or a group of theformula - CH (R[err]) - wherein R[err] represents a group of the formula R[err] - O - R[err], R[err]representing a bivalent hydrocarbon group having 1 to 30 carbon atoms, and R[err]representing a monovalent hydrocarbon group having 1 to 30 carbon atoms; Xrepresents:[err]n isan integer of 1 to 5; m is an integer of 1 to 100; 1 is an integer of 1 to 5; k is an integerof 0 to 100; a is an integer of 0 or 1; j is an integer of 1 to 50; and i is the valency of R1.
