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 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.
