Abstract

See full text

The present invention relates to novel degradable branched-block copolymers, comprising a star-shaped copolymer central core or a linear copolymer central core, functionalized with photoreactive groups chosen among aryl-azide, (meth)acrylate or thiol groups. The present invention also relates to the use of these degradable branched-block copolymers as photo-crosslinkers to provide degradable photo-crosslinked elastomers as biomaterials suitable for medical and tissue engineering applications. A method for preparing a degradable photo-crosslinked polymer, preferably a degradable photo-crosslinked elastomer, starting from the branched-block copolymer of the invention via a shaping process and an irradiation step is also provided.
