Patent ID: 7910683

Claim:
A polysiloxane(amide-ureide) polymer which inhibits the ability of ice to adhere to a surface of a physical object, said polysiloxane(amide-ureide) polymer comprises a backbone comprising the reaction product of the following: (i) at least one diamine-terminated polysiloxane of the general formula: wherein, for each unit of the polysiloxane R 1 and R 2 are independently selected from the group consisting of C 1 to C 10 alkyls, aryls, and polyaryls; for each unit of the polysiloxane R 3 and R 4 are independently selected from the group consisting of hydrogen, C 1 to C 6 alkyls, aryls, C 3 to C 6 cycloaliphatics, and C 3 to C 6 heterocycles; for each unit of the polysiloxane A 1 and A 2 are independently selected from the group consisting of hydrogen, C 1 to C 6 alkyls, aryls, polyaryls, C 3 to C 6 cycloaliphatics, and C 3 to C 6 heterocycles; for each unit of the polysiloxane, x is a number from 1 to 1000; (ii) at least one an aromatic diamine; (iii) at least one diisocyanate; and (iv) at least one halide substituted dicarboxylic acid.
