ABSTRACT:
The present invention relates to biodegradable biocompatible polyacetals, methods for their preparation, and methods for treating mammals by administration of biodegradable biocompatible polyacetals. A method for forming the biodegradable biocompatible polyacetals combines a glycol-specific oxidizing agent with a polysaccharide to form an aldehyde intermediate which is combined with a reducing agent to form the biodegradable biocompatible polyacetal. The resultant biodegradable biocompatible polyacetals can be chemically modified to incorporate additional hydrophilic moieties. A method for treating mammals includes the administration of the biodegradable biocompatible polyacetal in which biologically active compounds or diagnostic labels can be disposed.
