Membranes or matrices made of a siloxane-based elastomer for the control of drug penetration, wherein said elastomer comprises 3,3,3-trifluoropropyl groups attached to the silicon atoms of the siloxane units. A process for preparing a siloxane polymer comprising 3,3,3-trifluoropropyl substituents, wherein said elastomer is for controlling drug penetration. In this way, a 3,3,3-trifluoropropyl substituted polysiloxane component with vinyl as a functional group and a silicon hydride crosslinking agent as a functional group in the presence of a catalyst, or a 3,3,3-trifluoropropyl substituted polysiloxane component in the presence of a peroxide catalyst |
