Abstract
The present invention concerns a method for the preparation of a product based on a crosslinked polymer, comprising a step for crosslinking said polymer or one of its physiologically acceptable salts in the presence of a crosslinking agent comprising at least two epoxy functions, said crosslinking being carried out at a temperature of more than 0° C. and less than 10° C., as well as the implantable or injectable products obtained therefrom, advantageously based on hyaluronic acid.
Claims19
A method of preparing a product containing a crosslinked polymer, wherein the crosslinking step consists in incubating in a reaction mixture the polymer, or one of its physiologically acceptable salts, with a crosslinking agent having at least two epoxy functions, at a temperature of more than 0° C. and less than 10° C., advantageously between 1° C. and 9° C.
