ABSTRACT:
A polysiloxane(amide-ureide) which inhibits the ability of ice to adhere to a surface of a physical object when applied to a surface of a substrate. The polysiloxane(amide-ureide) has a backbone including:(i) at least one diamine-terminated polysiloxane of the general formula:wherein, for each unit of the polysiloxane R1and R2are independently selected from the group consisting of C1to C10alkyls, aryls, and polyaryls; for each unit of the polysiloxane R3and R4are independently selected from the group consisting of hydrogen, C1to C6alkyls, aryls, C3to C6cycloaliphatics, and C3to C6heterocycles; for each unit of the polysiloxane A1and A2are independently selected from the group consisting of hydrogen, C1to C6alkyls, aryls, polyaryls, C3to C6cycloaliphatics, and C3to C6heterocycles; for each unit of the polysiloxane, x is a number from 1 to 1000;(ii) at least one aromatic diamine;(iii) at least one diisocyanate; and(iv) at least one halide substituted dicarboxylic acid.
