Abstract:
A process for the manufacture of a molding, which comprises the following steps:a) providing at least one prepolymer comprising one or more crosslinkable groups, wherein the prepolymer is an amphiphilic segmented copolymer comprising at least one hydrophobic segment and one hydrophilic segment;b) preparing an at least partly bicontinuous mesophase of the prepolymer by combining the prepolymer with an aqueous solution at a ratio that will give a microstructure which is at least partly bicontinuous and causing or allowing the bicontinuous microstructure to form;c) introducing the mesophase obtained into an ophthalmic mold;d) crosslinking the prepolymer to form the molding; ande) opening the mold such that the molding can be removed.
