    摘要: The mousse hair composition of the invention comprises a resin provided by about 3-15% by weight of about a 20-50% alcoholic solution of the half-alkyl ester of a C.sub.1 -C.sub.5 alkyl vinyl ether-maleic anhydride copolymer having a molecular weight of at least one million, which is about 5-90% neutralized, preferably with about 0.15-1.0% by weight of ammonium hydroxide, about 60-95% by weight of water, about 0.3-2.0% by weight of a surfactant, and about 0-30% by weight of added ethanol.

    摘要: Slurry copolymerization of maleic anhydride with (meth)acrylic acid and, optionally, with C.sub.1 -C.sub.4 alkyl vinyl ether in a cosolvent system of cyclohexane and ethyl acetate yields a pumpable slurry, from which uniform, fine, white powders having a predetermined weight average molecular weight of about 10,000 to one million, preferably about 30,000 to 400,000, are obtained.
