Patent ID: 7910129

Claim:
A synthetic absorbable macromer composition comprising: an acid-functional polymer of formula (I): where R 1 can be the same or different at each location and is selected from the group consisting of polyalkylene oxides, polyethylene glycols having degradable linkages, and polyethylene oxide-polypropylene oxide copolymers; an amine-functional polymer comprising a polyalkylene oxide having at least one pendant amine group and a non-pendant, non-terminal, intra-backbone stiffening linkage, the stiffening linkage selected from the group consisting of phthalic groups, bisphenol A, biphenyl groups, diglycidyl ethers of bisphenol A, ethoxylated bisphenol A, terephthalic acid, phenylene diamine, and imides; and a coupling agent comprising a carbodiimide.
