摘要： Polymer-coated medical and laboratory devices are disclosed which are characterized by their biocompatibility and resistance to nonspecific protein adsorption. The polyurea-polyurethane coatings of this invention are prepared from high molecular weight isocyanate end-capped prepolymers substantially or exclusively comprised of ethylene oxide units. At least 75%, preferably at least 90%, of the prepolymer units are oxyethylene-based diols or polyols having molecular weights of about 7000-30,000, with essentially all of the hydroxyl groups capped with polyisocyanate prior to formation of the hydrated polymer coating.

摘要： A method of preparing a hydrophilic, biocompatible contact lens characterized by a surface which resists nonspecific protein adsorption. The method involves forming a prepolymer, at least 75% of which are oxyethylene-based diols and polyols having molecular weights of about 7000 to about 30,000. The prepolymer is subsequently gelled and hydrated to produce a hydrated polyurea-polyurethane polymer gel. The hydrated polymer gel is used to obtain a contact lens which resists nonspecific protein adsorption. Preferably, the contact lens are prepared by molding the prepolymer into a contact lens mold, prior to polymerization, to achieve the desired lens shape.

摘要： The invention disclosed is for a new and novel class of liquid polyene compositions formed of a molecule containing at least two unsaturated carbon-to-carbon bonds disposed at terminal positions on a main chain backbone of the molecule. The molecule includes unsaturated carbon-to-carbon bonds connected by a divalent chemically compatible derivative to a stable, organic, polyvalent, and polymeric member free of reactive carbon-to-carbon unsaturation and free of highly water-sensitive members. The new class of liquid polyene compositions which have a molecular weight in the range 300 to 20,000, and a viscosity in the range from essentially 0 to 20 million centipoises at 70.degree.C., may usefully form a component of a system which upon curing in the presence of a free radical generator and a polythiol, forms odorless, solid, elastomeric products. The cured products may be used as sealants, coatings, adhesives and molded articles.
