    Abstract: A charge imbalanced composition comprising: (a) about 10 to 90 mole % of a mixture of amphoteric copolymers having formulas (I) and (II) where A is present in an amount of about 0.1-0.8 mole, and B is present in an amount of about 0.05-0.4 mole, and where A is 2-6 times B, where R=C1-C4, n=1-6, R1 and R2 are independently C1-C6, R3 is H or lower alkyl, and R4=C12-C24; (b) about 10 to 90 mole % of a polymeric diacid having formula (III) where R is as defined above, and (c) about 0-20 mole % of by-product salts which are the dialkylaminoalkylamine and alkylamine salts of (a) and (b). The composition described above is made by: reacting 1 mole of an anhydride compound having formula (IV) where R is as defined above, with less than 1 mole of a mixture of about 0.1-0.8 mole of a compound having formula (A) where n, R1, R2 and R3 are as defined above, and about 0.05-0.4 of a compound having formula (B) where R4 is as defined above, and where A is 2-6 times B, isolating the product, and hydrolyzing any residual anhydride compound in water to the corresponding diacid compound.

    Abstract: A process is described for making substantially homogeneous copolymers comprising 20-99 % of vinyl pyrrolidone (VP) and 1-80 % of N-3,3-dimethylaminopropyl methacrylamide (DMAPMA), preferably 50-95 % VP and 5-50 % DMAPMA, and, most preferably, about 80:20, by weight, having a weight average molecular weight of about 200,000 to 1,500,000, as a clear, low viscosity aqueous solution of the homogeneous copolymer, at a 5-20 % solids level, preferably about 10-15 %, by weight of the solution, having a viscosity of about 5,000 to 80,000 cps, preferably about 10,000 to 70,000 cps. The solution obtained herein has lower viscosity and better clarity, and provides hair care products with enhanced curl retention (hold), when compared to non-homogeneous copolymers of the same composition, or related existing commercial products.
