Zusammenfassung:	Methods of modifying polyurethanes using surface treated clay are disclosed herein. Such methods can be useful for controlling the surface concentration of one or more additives in the polyurethane, which can be useful for fabricating medical devices therefrom. L'invention concerne des procédés de modification de polyuréthannes utilisant une argile à surface traitée. De tels procédés peuvent être utiles pour moduler la concentration de surface en un ou plusieurs additifs dans le polyuréthanne, ce qui peut être utile pour la fabrication des dispositifs médicaux.
