    摘要: Copolymers having improved machining and water resistant properties are produced using a monomer containing an adduct protecting group, particularly an alkyl boronic acid adduct, of glyceryl acrylate or glyceryl methacrylate, in combination with an alkyl acrylate or methacrylate, and optionally a glycidyl acrylate or methacrylate. After machining and shaping, the adduct is removed to provide a hydrogel useful as a contact lens material.

    摘要: The invention provides new hydrogel forming materials comprising synthetic, hydrophilic, aqueous-insoluble polymer networks formed by copolymerization of a hydrophilic dihydroxyalkyl acrylate or methacrylate, a substantially water insoluble alkyl acrylate or methacrylate, one or more additional hydrophilic comonomers selected from the group of vinylic monomers, acrylates, and methacrylates, and a cross-linking agent. The hydrogels are preferably used for the formation of contact lenses, but may also be used for drug and pesticides delivery devices; dialysis, ultrafiltration and reverse osmosis membranes; implants in surgery and dentistry; and the like.

    摘要: The invention provides a method of treating hydrogels formed from the polymerization of monomers having reactive olefinic double bonds by contacting them with reactive thiol compounds. In a preferred embodiment where the hydrogel structure includes a cis-glycol containing unit, a suitable thiol is used in conjunction with a borate buffer. The present invention also provides materials that are treated with the above thiol compounds.

    摘要: A method for resisting neurological damage caused by overstimulation of theMDA receptor of nerve cells by glutamate includes exposing the NMDA receptors to an oxidizing agent to thereby diminish overall activity of the receptors following activation by glutamate. The oxidizing agent preferably is a material selected from the group consisting of pyrroloquinoline quinone and topa hydantoin.
