Abstract
A hydrolytically unstable, biocompatible polymer capable of carrying and releasing a pharmaceutical compound when introduced into physiological media. In a preferred embodiment, the polymer contains ester linkages that are susceptible to hydrolytic degradation. A monomeric unit of the polymer can also be used as a hydrolytically unstable linking agent for quickening the degradation of polymers, particularly cross-linked polymers.
