ABSTRACT:
The present invention relates to methods for providing shaped biodegradable and elastomeric structures of (co)polymers of 1,3trimethylene carbonate (TMC) with improved (mechanical) properties which can be used for tissue or tissue component support, generation or regeneration. Such shaped biodegradable elastomeric structures are obtainable by forming homopolymers and/or copolymers of 1,3-trimethylene carbonate (TMC) into a desired shape and irradiating said desired shape with actinic radiation in an inert atmosphere.
