Abstract: Copolymer (I) for use as hair fixative is obtd. by free radical polymerisation of (A) 20-60 (wt)% vinyl-pyrrolidone (II), (B) 20-60% N-mono- or di-alkylated acrylamide(s) (III) with 1-8C alkyl gp(s), (C) 5-60% 1-4 C-alkyl or 2-4C hydroxyalkyl (meth)acrylate(s) (IV) or 3-12% (meth)acrylic acid (V) and opt. 2-48% (IV). (I) is soluble in 1-4C alcohols and has a K value of 15-75. (I) is prepd. from 30-50% (II), 30-50%(III) and 20-40% (IV) or 5-10% (V) and opt. 15-35% (IV) and has a K value of 20-50. 50-100% of the free COOH gps. in (I) are neutralised with a 2-9C mono-, di- or trialkanolamine. The hair fixative contains 0.5-5, esp. 1.0-5.0% (I), pref. together with 50-75% solvent and 25-50% propellant gas.

Abstract: Copolymers of vinylpyrrolidone, acrylamides which are monoalkylated or dialkylated on the N atom and alkyl or hydroxyalkyl esters of (meth)acrylic acid, with or without (meth)acrylic acid, or (meth)acrylic acid are used as and in hair fixatives.
