    • A new composition of matter specially adapted for the production of contact lenses, artificial eyes or other prosthetic devices. The composition has the characteristics of increased hydrophilicity, softness after hydration and oxygen permeability. The composition is a solid copolymer of comonomers consisting essentially of about 15 to about 65 parts by weight of one or more of the hydrophilic amide group containing monomers and about 10 to about 75 parts by weight of one or more of the copolymeric organosiloxane. Optionally, about 0.1 to about 65 parts by weight of at least one property modifier, a vinyl group containing monomer such as methyl methacrylate, can be employed into the copolymers. The inventive material is optionally transparent, translucent or opaque depending on the type, composition and relative content of the comonomers used. In general, the transparent composition is suitable for use in making contact lenses.
    • 专门用于生产隐形眼镜,人造眼睛或其他假肢装置的新物质组合物。 该组合物具有增加的亲水性,水合后的柔软性和透氧性的特征。 该组合物是共聚单体的固体共聚物,其基本上由约15至约65重量份的一种或多种亲水性酰胺基单体和约10至约75重量份的一种或多种共聚有机硅氧烷组成。 任选地,可以在共聚物中使用约0.1至约65重量份的至少一种性质改性剂,含乙烯基的单体如甲基丙烯酸甲酯。 根据所使用的共聚单体的类型,组成和相对含量,本发明的材料可选地是透明的,半透明的或不透明的。 通常,透明组合物适用于制造隐形眼镜。
