This invention provides tobacco compositions which contain a flavorant-release oligomeric and polymeric derivative corresponding to the structural formula: <IMAGE> wherein R is a member selected from the group consisting of hydrogen and aliphatic, alicyclic and aromatic hydrocarbon radicals containing between 1 and about 10 carbon atoms, with the proviso that R is hydrogen when m is zero; R1, R2, R3 and R4 are members selected from the group consisting of hydrogen and aliphatic, alicyclic and aromatic hydrocarbon radicals; and m and n are integers. |
