Patent ID: 7858728

Claim:
A polycarbonate, wherein the polycarbonate comprises a terminal olefin group of the formula wherein R 1 is a C 1 -C 40 hydrocarbon that can be unsubstituted or substituted with a halogen, olefin, ether, or a C 4 -C 30 polyoxyalkylene functionality in which the alkylene groups contain 2 to 6 carbon atoms, and R 2 to R 4 are each independently a hydrogen or a C 1 -C 40 hydrocarbon that can be unsubstituted or substituted with halogen, olefin, ether, or C 4 -C 30 polyoxyalkylene functionality in which the alkylene groups contain 2 to 6 carbon atoms, optionally wherein any two of R 1 to R 4 together form a monocyclic, bicyclic, or tricyclic ring system optionally substituted with a heteroatom in the ring; and wherein the polycarbonate comprising the terminal olefin group is the reaction product of a carbonate and a compound of the formula or a combination comprising at least one of the foregoing formulas at a temperature and for a time effective to form the terminal olefin group.
