Tetrapolymers comprising (a) unsaturated acids (b) vinyl esters (c) branched allyl or methallyl esters and (d) vinyl ether or vinyl fatty ester or linear allyl or methallyl esters

摘要: Copolymer of (a) an unsaturated acid having the formula R--CH ═ CH--(CH 2 --O--CH ) n --COOH wherein = 0 or 1, and when O, R CH 3 H, (b) a vinyl ester ##STR1## is C H 5 , (c) at least one branched allyl methallyl ##STR2## R' represents hydrogen 1 saturated hydrocarbon chain, linear branched, -6 carbon atoms CH(CH with proviso that sum number in +R equal to less than 7 (d) monomer selected from group consisting ether CH--O--R alkyl 1-12 atoms, fatty chain ##STR3## 4 7-11 ##STR4## 1-11 atoms. The copolymer employed cosmetic carrier vehicle provide composition for hair, such as hair lacquer setting lotion, generally amount about 1-4 weight percent composition.
