    摘要: The subject matter of the present invention is an amphiphilic, segmented copolymer of controlled morphology comprising at least one segment having high oxygen permeability, at least one segment having high ion and water permeability, the segments being linked together through a non-hydrolizable bond, and at least one polymerizable unsaturated group; a process for the preparation of the copolymer; to polymeric products obtainable by further polymerizing and optionally cross-linking the amphiphilic segmented copolymer, and to mouldings, especially contact lenses and other ophthalmic devices comprising a polymeric product of the invention. In a specifically preferred embodiment, the present invention relates to a contact lens comprising a polymeric product of the invention which is suited for extended periods of wear.
