PROCEDE DE MODIFICATION DE POLYSACCHARIDES PAR GREFFAGE DE POLYETHERAMINES, POLYSACCHARIDES AINSI MODIFIES ET PREPARATIONS LES COMPORTANT ET PRESENTANT DES PROPRIETES RHEOLOGIQUES THERMOSENSIBLES
A modification of natural or synthetic polysaccharides by grafting polyetheramines, and the use of modified polysaccharides in the form of a hydrogel as a medium for cell culture. These hydrogel preparations may have heat-sensitive rheological properties that are interesting for their intracorporeal use in human and veterinary medicine, for cell culture and transport of biological samples.
