    摘要： Silane-modified polyvinyl acetals are obtained by copolymerizing a) vinyl esters of C1-15 alkylcarboxylic acids having from 1 to 15 carbon atoms, and optionally (meth)acrylates C1-15 of alcohols, olefins, dienes, vinylaromatics, or vinyl halides, with b) from 0.02 to 20.0 % by weight of an ethylenically unsaturated, hydrolyzable silicon compounds or hydrolyzable mercaptosilanes; hydrolyzing the resulting vinyl ester copolymers to 50 mol % or more of vinyl alcohol units; and acetalizing vinyl alcohol units with a C1-15 aliphatic or aromatic aldehydes, wherein from 5 to 50 % by weight of a mixture of comonomers a) and silane comonomers b), based on the total weight of comonomers a) and b), is used as an initial charge, and the remainder is metered in during polymerization, such that the ratio between the comonomers a) and silane comonomers b) remains constant throughout the polymerization, resulting in a homogeneous polymer.

    摘要： A process for producing a low cross-linking-density gel capable of effectively inhibiting light scattering in joining the ends of optical fiber cores with each other. The process is characterized by involving the compounding step for adjusting a flexible silicone gal material to have a specified refractive index and the reaction step for cross-linking the flexible silicone gel material obtained in the above step in a binding region with a low cross-linking density, thus yielding a low cross-linking-density gel.

    摘要： The present invention relates to photocurable siloxane polymers having functional acryl groups, useful in the preparation of intraocular lenses (IOLs). The polymers are siloxane copolymers, wherein the siloxane can be selected from the group consisting of diphenyl siloxane, phenylalkyl siloxane, dialkyl siloxane, and trifluoroalkyl alkyl siloxane. The invention also relates to methods for producing the said siloxane polymers, as well as to producing accommodating lenses in vivo, which means that the tens is formed in the capsular bag of the eye.
