Abstract
The present application describes novel antifouling coating compositions comprising carbon-based hydrolysable polymers of ethylenically unsaturated monomers of which some include cyclic carbonates or cyclic ethers, e.g. (2,2-dimethyl-1,3-dioxolan-4-yl)methyl (meth)acrylate (IPGA/IPGMA), isopropylidene glycerol ethoxylated acrylate (iPGEOA), isopropylidene glycerol N ethoxylated methacrylate (iPGEOMA) and (2-oxo-1,3-dioxolan-4-yl)methyl (meth)acrylate (GCA/GCMA), and their use in antifouling coating compositions. Novel polymers are also described.
Claims24
An antifouling coating composition comprising a polymer of ethylenically unsaturated monomers, said monomers including at least one monomer of the general formula I
- wherein m is 0-50, n is 1-3, R1 is selected from hydrogen and methyl, and X is selected from >C═O or >C(R2)(R3), where R2 and R3 are independently selected from hydrogen, C1-20-alkyl and aryl.
An antifouling coat comprising a polymer of ethylenically unsaturated monomers, said monomers including at least one monomer of the general formula I
- wherein m is 0-50, n is 1-3, R1 is selected from hydrogen and methyl, and X is selected from >C═O or >C(R2)(R3), where R2 and R3 are independently selected from hydrogen, C1-20-alkyl and aryl, and one or more pigments and fillers.
The use of one or more polymer(s) of ethylenically unsaturated monomers, said monomers including at least one monomer of the general formula I
- wherein m is 0-50, n is 1-3, R1 is selected from hydrogen and methyl, and X is selected from >C═O or >C(R2)(R3), where R2 and R3 are independently selected from hydrogen, C1-20-alkyl and aryl,
- as a co-binder for improving the antifouling properties of a coating composition comprising an erodible binder system.
