FIELD: chemistry.
SUBSTANCE: new cyclic carboxylic acid is obtained in reaction which includes performing connection [J] of, at least one terpen-based diene connection (conjugate diene connection), chosen from group consisting of alloocymen, ocymen, mircen, α-terpinen and α-phellandren, and [K], at least one unsaturated carboxylic acid, chosen from α,β-unsaturated carboxylic acids and monoethers of α, β-unsaturated dicarboxylic acids. Connecting agent (A) for antifouling paint is also revealed. It containes one or more substances chosen from new cyclic carboxylic acid, derivative from cyclic carboxylic acid (excluding metal salt), metal salts of cyclic carboxylic acid and metal salts of the derivative of cyclic carboxylic acid, as well as composition of antifouling paint, which contains connecting agent (A) and copolymer (B) for antifouling paint of self-cleaning type, which is a polymerising copolymer based on basic metal salt of unsaturated carboxylic acid or polymerising unsaturated copolymer based on silyl ether of unsaturated carboxylic acid. From composition of antifouling paint covering film can be formed, which has only slight influence on environment, it is evenly subjected to erosion with definite rate, is able to retain excellent properties against fouling for a long period of time and can be applied to the surfaces of ships and other objects, which are used in marine territories with high risk of fouling.
EFFECT: obtaining film of antifouling paint, which has only slight influence on environment, is evenly subjected to erosion with definite rate, is able to retain excellent properties against fouling for a long period of time.
