ABSTRACT:
Biodegradable alkyloxycarbonylmethyl or aryloxycarbonylmethyl polyaspartate and polyglutamate which can be used as a carrier for drugs which are either in the encapsulated state or are incorporated in the polymer matrix. The polypeptide thus loaded degrades enzymatically in the organ where it has been placed and thus gradually releases the drug which it contains.
