Claims18
A method for manufacturing a cross-linked polymer of at least one carbohydrate component comprising at least one primary alcohol function, said method comprising cross-linking in an aqueous phase at least one primary alcohol function of the carbohydrate component with at least one reactive function of a cross-linking agent to obtain the cross-linked polymer of said carbohydrate component.
A method for manufacturing a cross-linked polymer of at least one carbohydrate component comprising at least one primary alcohol function, said method comprising dissolving a carbohydrate component comprising at least one primary alcohol function in an aqueous phase, and then admixing with said aqueous phase a phase containing a cross-linking agent having at least one reactive function, for a period of time sufficient to obtain a cross-linked polymer of said carbohydrate component having a molecular weight of greater than or equal to 50,000 Daltons.
