Claims26
1-77. (canceled)
A method of making a polymer composition, comprising polymerizing a first compound having either one or two cyclic ether groups having the structure
- in which n is 1-4 and no additional reactive groups, with a second compound that is the same or different from the first compound, comprising one or two carboxyl groups and no additional reactive groups, wherein if the first compound has only one cyclic ether group, then it also comprises a carboxyl group and the second compound comprises a cyclic ether group having the structure
- in which n is 1-4.
A biological scaffold or drug delivery vehicle comprising a polymer composition according to claim 98.
A polymer composition comprising the structure [—OC(O)—B′—CH(OR1)-B—]n or —[OC(O)—B—C(O)O—CH2—CH(O—R1)-CH2—B′—CH2—CH(O—R2)-CH2—]n, in which B and B′ are the same or different and are organic groups, or B′ is not present, and R1 and R2 are the same or different and are hydrogen or a functional group.
