Claims
- 1. A process for producing catalyst-free resorbable homopolymers or copolymers comprising the steps of: (a) dissolving a catalyst-containing polymer in an organic solvent which is immiscible with water, (b) bringing the thus dissolved polymer into intimate contact with water or with an aqueous phase which contains an inorganic acid, a water-soluble organic acid or a water-soluble complexing agent, (c) separating the organic phase from the aqueous phase, and (d) isolating the polymer from the organic phase.
- 2. The process as claimed in claim 1, characterized in that the acid or the complexing agent is present in the aqueous phase in a concentration of from about 0.1 to 5%.
- 3. The process as claimed in claims 1 or 2, characterized in that the concentration of the dissolved polymer in the organic solvent does not exceed about 10%.
