Abstract:
A polymer which inhibits the ability of ice to adhere to a surface of a physical object, said polymer formed from repeat units having the formula: wherein for each repeat unit of the polymer, R1 and R2 are independently selected from the group consisting of C1 to C10 alkyls, aryls, and polyaryls; for each repeat unit of the polymer, R3 and R4 are independently selected from the group consisting of hydrogen, C1 to C6 alkyls, aryls, C3 to C6 cycloaliphatics, and C3 to C6 heterocycles; for each repeat unit of the polymer, A1 and A2 are independently selected from the group consisting of hydrogen, C1 to C6 alkyls, aryls, polyaryls, C3 to C6 cycloaliphatics, and C3 to C6 heterocycles; for each repeat unit of the polymer, x is a number from 1 to 1000; and for each repeat unit of the polymer, Y is selected from a dicarboxyl residue and a non-linear diisocyanate residue, and wherein the polymer comprises at least one repeat unit where Y is a dicarboxyl residue and at least one repeat unit where Y is a nonlinear diisocyanate residue.
