摘要： The invention relates to biodegradable polycondensates, to the production of said polycondensates, and to their use for releasing specific substances. The polycondensates are derived from at least three components chosen from the following group: a) dianhydrohexites b) bivalent (polyvalent) organic carboxylic acids and c) polyvalent organic carboxylic acids which, in addition to two carboxylic acid functions, have at least one other, optionally capped, i.e., OH and/or COOH function.
