The science of biodegradable materials is most often associated with problems of environmental control. The need to avoid accumulation of permanent ecological litter is obvious and methods to do so will not be considered in this discussion. Rather, the emphasis will be on polymers with the potential for degradation within the living organism. More specifically, polymers which display structural integrity and, as a consequence, mechanical utility, will be considered while polymeric drugs or carriers which function in solution, such as polyvinyl pyrollidone and dex-tran, both reported as useful blood extenders, will not. |
