摘要
Novel polymers for biomedical use, especially rigid gas permeable contact lenses that are based on bulky side-chain siloxane cross linkers. The siloxanes, either alone, or as copolymers with bulky and non-bulky mono-functional polymerizable siloxanes, fluoro monomers, such as hexafluoroisopropyl methacrylate, and hydrophilic monomers, result in transparent, high oxygen permeable polymers possessing excellent lathing and milling characteristics.
