US 2003/0158358 A1 · Copolymers containing fluoro and silyl groups and their use in marine antifoulant composition

Abstract

Copolymers of at least three monomer units selected from the group consisting of fluorinated acrylic (methacrylic) monomers, triorganosilylacrylic (e.g. trimethylsilyl methacrylate) monomers and acrylic monomers not containing an organosilyl moiety, (e.g. methyl methacrylate) and optionally containing from 0-5 weight percent of a cross-linking agent are novel compositions useful as polymeric binders in long life marine antifoulant coatings. The erosion rate and resistance to cracking of the copolymer of the present invention when used as a binder in a marine antifoulant paint is controlled by adjusting the proportions of each monomer and the amount of crosslinking agent in the copolymer of the present invention

Dependent claims

A polymer suitable for use as a marine antifouling coating comprising a copolymer of:

a. a monomer of the formula:
7
wherein R is CH3 or H, and RF is (C)u(CH)v(CH2)w(CF)x(CF2)y(CF3)z where u is from 0 to 1, v is from 0 to 1, w is from 0 to 20, x is from 0 to 1, y is from 0 to 20, z is from 1 to 3, and the sum of w and y is from 0 to 20,
b. a monomer of the formula:
8
wherein R is CH3 or H, and R1 alkyl, aryl, etc.
c. a monomer of the formula:
9
wherein R is CH3 or H, and R1, R2, and R3 can be the same or different and are non-hydrolysable alkyl groups containing from 1 to 20 carbon atoms and/or a non-hydrolysable aryl groups containing from 6 to 20 carbon atoms.
