Abstract

The present invention relates to the discovery of new class of hydrolysable amino acid derivatives and absorbable polyester amides, polyamides, polyepoxides, polyureas and polyurethanes prepared therefrom. The resultant absorbable polymers are useful for drug delivery, tissue engineering, tissue adhesives, adhesion prevention, bone wax formulations, medical device coatings, stents, stent coatings, highly porous foams, reticulated foams, wound care, cardiovascular applications, orthopedic devices, surface modifying agents and other implantable medical devices. In addition, these absorbable polymers should have a controlled degradation profile.
