NEW (METH)ACRYLIC RESIN COMPOSITIONS FOR MARINE ANTIFOULING PAINTS AND CORRESPONDING PAINT COMPOSITIONS

摘要

Sin (meth) acrylic resin compositions for marine antifouling paints, and corresponding paint compositions;The organosoluble (meth) acrylic resin composition is esterified with -Ti (OR) ₃ groups and introduced for the preparation of the polymer in an amount sufficient for the free composition of Ti (OR) ₄ (which is organic soluble and not gelled). Extra Ti (OR) ₄ , R represents one of ethyl, isopropyl, n-butyl, t-butyl, 2-ethylhexyl and t-amyl) Containing polymers. This is the product of esterification in the solvent of the polymer containing units derived from methacrylic acid of Ti (OR) ₄ (Ti / COOH molar ratio is at least 1, preferably 3/1 and 10/1); Or at least one methacrylic acid and at least one esterified with Ti (OR) ₃ in the presence of Ti (OR) ₄ , in an amount corresponding to the reaction of methacrylic acid with a molar ratio of 1 × (x1) and Ti (OR) ₄ It may be the product of radical copolymerization in the solvent of the comonomer of.
