Abstract: The prodn. of radiation-curable acrylates comprises (1) reaction of hydroxy cpds. with (meth)acrylic acid followed by (2) reaction with peroxide cpds. in presence of quat. ammonium or phosphonium cpds. of formula (I) or (II) as catalysts: X = counter-ion; R -R = 1-18C alkyl (opt. substd. with 1 or 2 Ph gps.) or 6-12C aryl (opt. substd. with 1 or 2 1-6C alkyl gps.). Also claimed are curable acrylates (A) obtd. by this process, and radiation-curable prepns. (B) contg. (A) and an isocyanate cpd. with at least 2 NCO gps. for subsequent crosslinking, pref. in amts. of 0.05-30 wt.%.

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.
