    摘要: The invention relates to a process for rendering contact lenses hydrophilic, which comprises treating a contact lens with a compound of formula IAr--Z--Ar' (I)wherein Ar and Ar' are each independently of the other an aromatic radical that may be substituted by lower alkoxy and/or by lower alkyl and wherein one of the radicals Ar and Ar' or both radicals Ar and Ar' contain one or more substituents X selected independently of one another from a polar functional group Y, lower alkyl substituted by a polar functional group Y, and lower alkoxy substituted by a polar functional group Y, and wherein Z is a divalent group that separates Ar and Ar' from each other by from one to six atoms. The invention relates also to contact lenses treated according to the invention and to the use of compounds of formula I in the process according to the invention.

    摘要: Materials and a method of their preparation are described, for use in immobilizing soluble, biologically active compounds. The material for immobilizing includes a hydrophobic, water insoluble substrate having a coating of a mixture of different amphiphilic lipoid compounds thereon. The lipoid compounds are oriented so that the hydrophilic portions are distal to the substrate and free to bond with water soluble proteins and carbohydrates.

    摘要: Molded foam bodies made of silicone can be produced in large series by means of known injection molding machines for liquid silicone by virtue of the fact that mixtures of ammonium carbonate, and/or ammonium carbaminate, and/or ammonium hydrogen carbonate, in powdered form, and at least one of the two liquid-paste-like components of liquid silicone are produced and the two liquid silicone components are then processed in the known manner, with the proviso that the mold is not completely filled with the dispersion.

    摘要: A procedure is described for wet chemical surface modification of formed articles and substrates coated with made of organopolysiloxanes: the articles formed were contacted with metal hydroxide solutions to tailor the binding capacity for ions, particularly metal ions, bivalent cations, organic macro anions, and organic macro cations, e.g. proteins. The procedure creates organopolysiloxane surfaces which are better wettable, have reduced surface resistance, are less sticky, are smoother and more biocompatible.
