Patent

CA 2343159

The present invention relates to polymers comprising one or more perfluoralkylpolyether units and one or more different charged units, to a process for producing such polymers in non-porous or particularly in porous form and to mouldings composed thereof. The novel polymers have an improved wettability and cell growth ability and are thus useful, for example, for the manufacture of biomedical devices, in particular ophthalmic devices.

La présente invention concerne des polymères comprenant une ou plusieurs unités perfluoroalkylpolyéther et une ou plusieurs différentes unités chargées. L'invention concerne également un processus de production de tels poylmères, non poreux ou particulièrement poreux, ainsi que des moules à base de ceux-ci. Par ailleurs, ces nouveaux polymères présentent une mouillabilité et une capacité de croissance cellulaire améliorées, et sont par conséquent utiles dans la fabrication de dispositifs biomédicaux, par exemple, et particulièrement de dispositifs ophtalmiques.
