Abstract (en)
[origin: WO2005012364A2] The invention concerns a complex matrix consisting of at least one crosslinked biocompatible polymer of natural origin whereon are grafted small chains of molecular weight less than 50000 Da with a grafting rate between 10 and 40 %, as well as a method for preparing a hardly degradable biocompatible matrix consisting of at least one polymer of natural origin, which consists in: grafting small chains of molecular weight less than 10000 Da, with a grafting rate between 10 and 40 %, and in mutually crosslinking the main chains of the polymer, to create a homogeneous matrix.
