Bifunctional modified biopolymer based polymers and hydrogels obtainable from such bifunctional modified biopolymer based polymers

Abstract

The invention relates to a bifunctional modified biopolymer based polymer, comprising at least one polymer chain comprising n first functional groups and m second functional groups. The first functional groups comprise groups able of being radically cross-linked following a free radical chain- growth polymerisation. The second functional groups comprise groups able to thiol-ene crosslinking. Preferred bifunctional modified biopolymer based polymers comprise bifunctional modified gelatin and bifunctional modified collagen. The invention further relates to a method to prepare such a bifunctional modified biopolymer based polymer and to a method to prepare a hydrogel starting from such bifunctional modified biopolymer based polymer. Furthermore the invention relates to hydrogels obtainable starting from such bifunctional modified biopolymer based polymers and to the use of such hydrogels.
