摘要：
A novel polymeric binder for an antifouling paint includes greater than 2.5 to less than 25 mole percent of a unit from a tributyltin acrylate or methacrylate monomer group, an acrylic or methacrylic ester monomer unit having selected substituent groups in the ester moiety so that the ester is hydrolyzable at a suitable rate in seawater, and a copolymerizable ethylenically unsaturated monomer unit.The presence of the hydrolyzable ester group in the polymer binder of the present invention enables the paint to erode at a desired rate in seawater even with the low tin content in the polymer, thereby providing a desired low level of tin in solution and exposing a fresh paint surface periodically.
