Stable emulsions and dispersions of both the water-in-oil and oil-in-water types are prepared by subjecting mixtures of the two phases to sheer stress in the presence of nitrile group-containing copolymers capable of forming hydrogels containing at least 90% by weight of water at room temperature. The present invention may be used in the preparation of emulsions and dispersions such as latex paints and adhesives; creams, lotions, and ointments in cosmetics and health care; cooling and lubricating emulsions, hydraulic fluids; emulsion polymerization medium for numerous important monomers; liquid membrane systems, drug delivery systems, implantable tissue augmentation and many others. Recently, one special group of emulsions, (liposomes) is being developed for targeted and controlled drug delivery. |
