Abstract: A stable, aqueous cationic hydrogel of, by weight, 1-50% of a crosslinked cationic copolymer of 5-95% vinylpyrrolidone (VP) and 5-95% 3-dimethylaminopropyl(meth)acrylamide (DMAPMA) monomers, a crosslinking agent in an amount of 0.05-1% of said monomers, and water is described. The hydrogel has a pH of about 10 and a Brookfield viscosity of about 650 (Model DV-II+, RV spindle #3, speed 10 rpm); it can increase its viscosity by up to 40x at a pH of 3-9 and absorb up to 200x its weight of water. The hydrogel also can effectively condition hair even in the presence of an anionic surfactant.

Abstract: This invention relates to a reactive diluent mixture employed in a free radical polymerization of film-forming monomers which comprises between about 25 and about 90 wt. % N-vinyl lactam containing 6 to 9 carbon atoms and between about 10 and about 75 wt. % of a non-cyclic vinyl amide having from 3 to 7 carbon atoms which is employed in a concentration of between about 10 and about 50 wt. % based on total film forming monomers.

Abstract: This invention relates to a process for the production of substantially odorless, color stable N-vinyl heterocyclic copolymer which includes contacting alcohol solution of the copolymer, under reduced pressure, with water and a reducing agent selected from the group of a nitrogen containing borane complex, sulfurous acid and an alkali metal salt of sulfurous acid and recovering an aqueous, 10-80 wt.% solids solution of the copolymer having a substantially color free stability for a period of more than a year. The invention also relates to an N-vinyl heterocyclic copolymer in substantially pure deionized water or in aqueous alcoholic solution which exhibits significantly reduced color and odor and which is obtained by contacting an alcohol-copolymer mixture with water and a nitrogen containing, trivalent boron complex compound and stripping alcohol from the resulting mixture.
