    摘要: What is described is a reactive extrusion process of making a polymeric hydrogel of a polymeric anhydride or acid, e.g. maleic anhydride or maleic acid polymer, or copolymer thereof, crosslinked with a crosslinking agent containing at least 2 crosslinkable groups, particularly, —OH or —NH2, or both. The reaction product is a crosslinked polymeric ester or amide/imide, or both, suitably having a mole ratio of —OH, or —NH2, to —COOH, of 1:10 to 10:1, preferably 2:10 to 7:1. The hydrogel is particularly swellable in water, e.g. >100% in 1 hour in aqueous media; and forms a thin, tacky layer on a substrate, which property is useful in bioadhesive products.

    摘要: A process of making a cosmetically or pharmaceutically-acceptable emulsion or gel composition which comprises: (a) heating a reaction mixture comprising, by weight, about 5-70% of a vinyl monomer in about 30-95% of an oil as solvent, wherein said oil is selected from the group consisting of a silicone oil, a mineral oil and a water-insoluble organic ester and a free radical initiator, optionally in the presence of a crosslinking agent and/or an oil soluble surfactant, with agitation, under an inert gas, at about 40-150° C., wherein the oil is present in an amount sufficient to keep the resultant vinyl polymer in a stirrable state until the end of the polymerization, (b) adding a surfactant, if a suitable surfactant was not present during polymerization, and, (c) then adding water to form an oil-in-water, a water-in-oil or a water-in-oil-in-water emulsion or gel, in a volume ratio of oil-in-water of 30:70 to 10:90, or water-in-oil of 90:10 to 30:70.
