Patent ID: 7915371

Claim:
A sealant material comprising a polymer formed from repeating units having the formula: wherein for each repeating unit of the polymer, R 1 and R 2 are independently selected from the group consisting of C 1 to C 10 alkyls, aryls, and polyaryls; for each repeating unit of the polymer, 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 repeating unit of the polymer, 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 repeating unit of the polymer, x is a number from 1 to about 10,000; and for each repeating unit of the polymer, Y is selected from a dicarboxyl residue and a diisocyanate residue such that about 40 mol % to about 60 mol % of the Y component within the polymer is a diisocyanate residue, wherein at least one of the diisocyanate residues is non-linear.
