ABSTRACT:
Copolymers having tertiary amine groups and composed of 16-43% methyl methacrylate, 25-54% dimethylamino ethyl methacrylate and 12-52% octadecyl methacrylate are particularly useful as hair treating resins with conventional carriers and additives. The copolymers can be crosslinked by up to 0.15 by an unsaturated agent to produce preferred copolymers used in wave-setting lotions in amounts of 1-3%. Such copolymers can also be partially or wholly quaternized by a quaternizing agent. Those copolymers not crosslinked are particularly useful as hair lacquers, especially in aerosol sprays in amounts of 1-4%. The molecular weight for the subject copolymers averages 10,000-1,500,000 and copolymerization can be effected in a solvent with a catalyst wherein the reaction mixture is heated for about 6 to 24 hours at about 80.degree. C. When applied to the hair, the amount of lotion or lacquer used can be 10-100 c.c. and the treated hair is rolled. After treatment, the hair holds its shape well and is easy to comb.
