Abstract:
A maleimide polymer comprises units derived from a maleimide derivative represented by the following general formula (I): where R<1> is a hydrogen atom or a methyl group, and R<2> is an alkyl, alkenyl or aryl group, each of which groups is substituted by at least one organosiloxane group or fluorine atom, or comprises a copolymer of (1) a maleimide derivative represented by the formula (I) but in which R<2> may be hydrogen or any optionally substituted aliphatic hydrocarbon or aryl group with (2) an alkyl or fluoroalkyl methacrylate or an organosiloxy styrene- or organosiloxy-(meth)acrylic acid derivative. The polymer material may be formulated into contact lenses high in oxygen permeability and having good mechanical properties.
