Abstract: A method for preparing a main chain scission-type polysilyl (meth)acrylate resin and application thereof. The method comprises: a cyclic monomer, vinyl monomer and vinyl silyl ester monomer are mixed in a solvent at a formulation ratio, then added a composite initiator in a mass percentage of 0.01-5% based on the total amount of the monomers, and reacted at a temperature of 25-150° C., and under the protection of argon or nitrogen gas, so as to prepare the main chain scission-type polysilyl (meth)acrylate resin, wherein the monomers are consisted of 5-95% by mass of cyclic monomer, 0-90% by mass of vinyl monomer and 5-95% by mass of vinyl silyl ester monomer. The resulting resin can not only be hydrolyzed on the side chain silyl ester segment under the effect of the sea water, but also occur chain scission on the main chain polyester segment under the effect of the seawater, so as to solve the dependency of the traditional self-polishing material on the sailing speed, effectively control the release of the antifouling agent at a constant rate, ensure the active substance preserved on the coating surface of the ships, and properly meet the antifouling requirements on the low sailing speed ships, submarines and off-shore oil platform facilities.
