Patent ID: 8137754

Claim:
A polyurethane comprising: a polymer containing at least one repeat unit derived from an isocyanate compound and at least one repeat unit derived from a hydroxyl-terminated thiocarbonate containing compound, said thiocarbonate containing compound having the formula: wherein c is 1 to 20; each R 4 and R 5 , independently, is optionally substituted, and is a linear or branched alkyl having from 1 to about 12 carbon atoms; or an aryl having from 6 to about 18 carbon atoms, optionally containing heteroatoms; or wherein said R 4 and said R 5 substituents, independently, contain an alkyl having from 1 to 6 carbon atoms, an aryl, a halogen, a cyano, an ether having from 2 to about 20 carbon atoms, a nitro, or combinations thereof, or R 4 and R 5 can form a substituted or unsubstituted cyclic ring having from 3 to about 12 carbon atoms; each R 14 is derived from a polyol, wherein said polyol comprises a hydrocarbon polyol wherein R 14 comprises an alkyl or an alkylene group, or a substituted alkyl or alkylene group having from 2 to about 200 carbon atoms, and wherein said substituted alkyl or alkylene group comprises oxygen, or a halogen; polyester polyol, polyether polyol, polyhydroxy polyester amide, hydroxyl-containing polycaprolactone, hydroxyl-containing acrylic interpolymer, hydroxyl-containing epoxide, polyhydroxy polycarbonate, polyhydroxy polyacetal, polyhydroxy polythioether, polysiloxane polyol, ethoxylated polysiloxane polyol, polybutadiene polyol, hydrogenated polybutadiene polyol, polyacrylate polyol, halogenated polyester polyol, or halogenated polyether polyol, or combinations thereof; and T is a divalent radical having a nitrogen atom directly attached to a carbon atom of the thiocarbonyl group.
