    Abstract: A cosmetic or pharmaceutical preparation containing a water soluble or water dispersible copolymer (A) obtainable by radical copolymerization of: (1) (meth)acrylic acid amide; (2) alpha-beta-ethylenically unsaturated amide group containing compounds starch, starch derivatives and their mixtures; and (3) at least one cosmetically acceptable carrier is new. A cosmetic or pharmaceutical preparation containing: (1) at least one water soluble of water dispersible copolymer (A) obtainable by radical copolymerization of (wt.%): (a) (meth)acrylic acid amide (5-90); (b) at least one alpha-beta-ethylenically unsaturated amide group containing compounds of formula R1-C(O)-NR2R3 (I) (0-85): (c) at least one component different from (a) and (b) with a copolymerisable unsaturated water soluble compound (0-40), where the sum of (b) and (c) is at least 5 wt.%, optionally in the presence of up to 25 wt.% on the total weight of components (a) and (b) of at least one water soluble component (d) selected from: (i) polyether containing compounds; (ii) polymers having at least one 50 wt.% repeating units derived from vinyl alcohol; and (iii) starch and starch derivatives and their mixtures; and (2) at least one cosmetically acceptable carrier. R1, R2 = CH2=CR4; R4 = H or 1-4C alkyl; R1, R2, R3 = H, alkyl, cycloalkyl, heterocycloalkyl, aryl or heteroaryl; provided that: (1) either R1 is CH2=CR4 and R2 is H, alkyl, cycloalkyl, heterocycloalkyl, aryl or heteroaryl or joined with R3 or R2 is C=R4 and R1 is H, alkyl, cycloalkyl, heterocycloalkyl, aryl or heteroaryl or joined with R3; and (2) both of R2 and R3 are not H. An Independent claim is also included for a copolymer A obtainable by radical polymerization of (wt.%)::(a) methacrylic acid amide (10-45) and (b) vinylpyrrolidone and/or vinylcaprolacatam (60-90), (c) at least one different from (a) and (b) copolymerisable unsaturated water soluble compound (0-25), optionally in the presence of up to 25 wt.% on the total weight of (a)-(d) of polymers (d2) and/or starch or starch derivatives.

    Abstract: Water-soluble or dispersible graft copolymers having a K-value of 30-70 are claimed, which are obtained by radical polymerization of specified acrylate monomers and carboxyl group-containing vinyl monomers with a prepolymer having a K-value of 30-50 and containing at least 30 wt.% homopolymerized vinyl pyrrolidone (or ring expanded analogs). Water-soluble or dispersible graft copolymers having a K-value of 30-70 are claimed, which are obtained by radical polymerization of monomers (A) with a prepolymer (B) having a K-value of 30-50. Monomers (A) comprise (a) 50-85 wt.% monomers of formula CH2=CR'-CO-X-C(CH3)3 (I), (b) 15-30 wt.% of at least one carboxyl group-containing vinyl monomer and (c) 0-25 wt.% of a radical polymerizable vinyl monomer of formula CH2=CR'-CO-X-R (II). Prepolymer (B) contains at least 30 wt.% homopolymerized monomer of formula (III). The weight ratio of A:B is 100:5 to 100:200 and the graft copolymer is at least partially neutralized. X = O or NR''; R', R'' = H or 1-6C alkyl; R = 6-30C alkyl; n = 1-3. An Independent claim is included for a hair fixing preparation comprising 0.5-20 wt.% of the graft copolymer, 0-10 wt.% of a commercially available hair polymer, 50-99.5 wt.% of an alcohol and/or water, 0-50 wt.% of a propellant in the form of propane/butane and/or dimethyl ether, 0-0.5 wt.% of a water-soluble or dispersible silicone compound and 0-0.2 wt.% conventional additives.
