    摘要: Optical components have a material-distribution gradient due to nanometer-size particles embedded in a solid matrix. The components are manufactured by forming a dispersion of nanometer-size particles in a liquid, curable matrix material, causing the particles to migrate in the matrix material on the basis of a potential difference to form a distribution gradient, and subsequently curing the matrix material, retaining the distribution gradient. The method is suitable for use in the manufacture of optical lenses with a refractive index gradient.

    摘要: Described is a process for preparing a molding suitable for optical purposes, which process comprises the conjoint free-radical polymerization of a precondensate (A) which is derived from at least one hydrolytically condensable silane (a) having at least one free-radically polymerizable group X, and of a monomer (B) having at least two free-radically polymerizable groups Y, the numerical ratio of groups X to groups Y being not greater than 5:1. The moldings obtainable by this process are characterized by high transparency and homogeneity, freedom from stress, scratch and abrasion resistance, high mechanical strength, etc.
