    摘要: The invention is related to a method for producing silicone hydrogel contact lenses with a stable lubricious hydrogel coating thereon. A method of the invention comprises forming a plasma-reactive hydrophilic polymer hybrid base coating having reactive functional groups on a silicone hydrogel contact lens and heating the silicone hydrogel contact lens with the hybrid base coating in an aqueous solution of a water-soluble and thermally crosslinkable hydrophilic polymeric material to form a stable lubricious hydrogel coating thereon.

    摘要: A composition contains (a) 1 to 40 weight percent of poly(phenylene ether) particles having a mean particle size of 1 to 40 micrometers; and (b) 60 to 99 weight percent of a polyoxymethylene; wherein polystyrene is absent from the poly(phenylene ether) particles; wherein the composition comprises less than 0.1 volume percent, based on the total volume of the composition, of particulate metals, metalloids, oxides thereof, and combinations thereof, wherein the metals and metalloids are selected from iron, copper, aluminum, magnesium, lead, zinc, tin, chromium, nickel, tungsten, silicon, gold, silver, platinum, and alloys thereof. The poly(phenylene ether) particles reduce the density and increase the char yield of the polyoxymethylene. When the composition is prepared at a temperature below the glass transition temperature of the poly(phenylene ether), increased flexural strength can also be obtained. The composition is useful as a molding composition for a variety of articles.
