Patent ID: 7754823

Claim:
A composition comprising a moiety selected from the group consisting of a carboxyl moiety attached to a carbon chain that is 8 to 23 carbons in length, wherein the chain contains at least one dioxanone ring system and one or more sites of unsaturation; an ester moiety attached to a carbon chain that is 8 to 23 carbons in length, wherein the chain contains at least one dioxanone ring system and one or more sites of unsaturation; and, a polyester containing at least two ester moieties each of which is attached to a separate carbon chain that is 8 to 23 carbons in length, wherein at least one of said chains contains at least one dioxanone ring system and one or more sites of unsaturation; said dioxanone being formed from two adjacent carbons in the chain and having the following general structure (I): wherein one of R 2 and R 3 is a carbonyl and the other of R 2 and R 3 is CR 4 R 5 , and, wherein R 4 and R 5 are independently selected from the group consisting of hydrogen, C 1-10 alkyl, C 1-10 alkoxy, C 6-10 aryl, hydroxy, heteroaryl, C 3-6 cycloalkyl, phenyl(C 1-4 )alkyl and wherein R 6 is hydrogen or C 1-4 alkyl; and R 7 is selected from the group consisting of hydrogen, C 1-10 alkyl, C 1-10 alkoxy, C 6-10 aryl, hydroxy, heteroaryl, C 3-6 cycloalkyl and phenyl(C 1-4 )alkyl.
