Abstract
La presente invención se refiere a polímeros que comprenden una o mas unidades de poliéter perfluoroalquílico, y una o mas unidades cargadas diferentes, a un proceso para producir estos polímeros en una forma no porosa, o particularmente en forma porosa, y a artículos moldeados compuestos de los mismos. Los polímeros novedosos tienen una mejor humectabilidad y capacidad para crecimiento celular, y por lo tanto, son útiles, por ejemplo, para la abricación de dipositivos biomédicos, en particular dispositivos oftálmicos.The present invention relates to polymers comprising one or more perfluoroalkyl polyether units, and one or more different charged units, to a process for producing these polymers in a non-porous, or particularly porous, form, and to molded articles composed of the themselves. The novel polymers have better wettability and capacity for cell growth, and are therefore useful, for example, for the coating of biomedical devices, in particular ophthalmic devices.
