Abstract
A (poly)oxyalkylene block silyl ester copolymer comprising silyl ester copolymer block units (A) and block units (B), the block units (a) comprising (a) component units derived from a polymerizable unsaturated carboxylic acid silyl ester, and (b) polymerizable unsaturated monomer units other than the component units (a), the block units (B) derived from particular mercapto compounds, and an antifouling paint comprising the (poly)oxyalkylene block silyl ester copolymer. The copolymer enables the formation of an antifouling coating film which exhibits less cracking tendency, excellent adherence, less peeling tendency and controlled hydrolysis rate resulting in excellent antifouling performance and properties.
