Abstract: An intraocular lens whose optic or optic and haptic are composed of a substantially soft polymer obtained by curing a composition comprising:(a) a dimethylsiloxane-phenylsiloxane copolymer having a vinyl group at each of the both terminals of the molecular chain,(b) a diorganopolysiloxane having at least three hydrosilyl groups in the molecule, and(c) an U.V. absorber.The intraocular lens obtained above has good intraocular stability, excellent biocompatibility, high optical properties and an U.V. absorbability closer to that of the human lens.By further incorporting a filler as the component (d), the intraocular lens has improved mechanical properties and higher intraocular stability.

Abstract: The present invention relates to a substrate for information-recording media, which is formed of a polymer containing a specific acrylate-based monomer as an essential component. Since the acrylate-based monomer has a rigid skeleton similar to that of bisphenol A, the substrate for recording media, formed of the polymer of such a monomer, has high hardness and excellent heat resistance. Further, due to six fluorine atoms that the acrylate-based monomer contains, the substrate has advantages of low water absorptivity and easy die removability.
