Beschreibung
Zusammenfassung:	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. La présente invention concerne un procédé de préparation d'un produit à base d'un polymère réticulé, comprenant une étape de réticulation dudit polymère ou de l'un de ses sels physiologiquement acceptables en présence d'un agent de réticulation comprenant au moins deux fonctions époxy, ladite réticulation étant réalisée à une température supérieure à 0 °C et inférieure à 10 °C, ainsi que les produits implantables ou injectables obtenus à partir de ces derniers, avantageusement à base d'acide hyaluronique.
