{PG,1 This invention provides carboxylic acid flavorant-release oligomeric and polymeric derivatives corresponding to the structural formula: {r1 {tc,1 {rb {ab,44 {m,1 {sb,25 {us,5 {ob,4 {mr,1 CH{HD 2{AB,4 {M,2 {AB,0 CH{HD 3{MR,2 {AB,8 O{MX,2 {AB,8 C{AD,4 O{MX,2 {AB,8 R{MR,2 C{AB,444 {SB,26 {US,5 {CB,4 {S,6 {BL,88 {HD n{re {PS {PS WHEREIN R is a member selected from aliphatic, alicyclic, and aromatic hydrocarbon radicals and n is an integer. The oligomeric and polymeric derivatives are stable when used in smoking products and on pyrolysis release the carboxylic acid flavorants to enhance the flavor and aroma of the smoke. |
