Patent ID: 8349966

Claim:
A marine substrate, comprising a polymer coating, wherein the polymer has the formula: PB-(L 1 -N + (R a )(R b )-L 2 -A(=O)−OR c ) n (X − ) n wherein PB is a polymer backbone; N + is a cationic center; R a and R b are independently selected from hydrogen, alkyl, and aryl; A(=O)—OR c is a hydrolyzable group, wherein A is selected from the group consisting of C, S, SO, P, or PO, and R c is an alkyl, aryl, acyl, or silyl group that may be further substituted with one or more substituents; L 1 is a linker that covalently couples the cationic center to the polymer backbone; L 2 is a linker that covalently couples the cationic center to the hydrolyzable group; X— is a counter ion associated with the cationic center; and n is an integer from about 10 to about 10,000.
