Patent ID: 8278400

Claim:
A polyamine cross-linked polysiloxane which is prepared by cross linking a copolymer using a polyamine, wherein the copolymer has the formula: wherein x is an integer from 0 to 100; y is an integer from 0 to 100; z is an integer from 0 to 100, t is an integer from 0 to 100; u is an integer from 0 to 100; x+y+z+t+u is at least 5; at least one of u, x and z is not zero; n is an integer from 0 to 50; m is an integer from 0 to 50; p is an integer from 0 to 50; a is an integer from 0 to 50; b is an integer from 0 to 50; c is an integer from 0 to 50; d is an integer from 0 to 50; e is an integer from 0 to 50; f is an integer from 0 to 50; at least one of n, m, p, a, b, c, d, e and f is not zero; X is a halide or an end cap group; Y is a halide or an end cap group; Z is a halide or an end cap group; L 1 , L 2 , and L 3 are linking groups; R 1 , R 2 , R 3 , and R 10 are independently C 1 -C 10 alkyl, cyclopentyl, cyclohexyl, benzyl, toluoyl, xylyl or phenyl; R 4 is hydrogen, C 1 -C 10 alkyl, cyclopentyl, cyclohexyl, benzyl, toluoyl, xylyl, or phenyl; R 5 is C 1 -C 10 alkyl, cyclopentyl, cyclohexyl, benzyl, toluoyl, xylyl, phenyl, or a cross linking group; R 7 is hydrogen, C 1 -C 10 alkyl, cyclopentyl, cyclohexyl, benzyl, toluoyl, xylyl, phenyl, or a cross linking group; R 6 , R 8 , and R 9 include independently a biocidal group that is toxic to organisms that cause fouling in an aquatic environment; a fouling release group; a texturizing group; or combination thereof.
