Novel compositions of resins (meth) acrylic for marine anti-fouling paints, and the corresponding compositions for paints.

摘要

This composition is soluble in the resin (meth) acrylic is characterized by the fact that it comprises a polymer comprising moieties derived from methacrylic acid esterified by groups - ti (or) 3, as a mixture with the ti (or) 4, which represents the excess of ti (or) 4 having been inserted for the preparation of the polymer in an amount sufficient for the resulting composition is soluble and not in the form of a gel; r representing one from among ethyl, isopropyl, butyl n -, -, 2 -; and t - amyl. It may be the product of esterification in a solvent medium of a polymer comprising moieties derived from methacrylic acid by ti (or) 4, the molar ratio ti / cooh being greater than 1, being preferably between 3 / 1 and 10 / 1; or the product of radical copolymerization in a solvent medium of at least one methacrylic acid esterified by ti (or) 3 and of at least one comonomer in the presence of ti (or) 4, in a quantity which would have matched to a reaction between the methacrylic acid and ti (or) 4 with a molar ratio of 1 / x, x & 1).
