What is described herein are derivatized polymers of .alpha.-olefin-maleic anhydride alkyl half-ester or full acid, preferably the isobutylene compound, optionally with repeat units of maleamic acid and/or its corresponding maleimide therein. These polymers are useful as fixatives in personal care products, such as hair spray compositions, particularly as one-phase, low VOC formulations in pump and aerosol systems, and in anhydrous, alcoholic, aqueous- alcoholic and in high hydrocarbon tolerant solvent formulations. In use, these hair spray compositions dry down to form clear, continuous and defectless films.
L'invention concerne des polymères dérivatisés d'alkyl-semi-ester d'anhydride alpha-oléfine-maléique ou de l'acide total, de préférence du composé isobutylène, renfermant éventuellement des unités répétées d'acide maléamique et/ou du maléimide correspondant. Ces polymères sont utiles comme fixateurs dans les produits d'hygiène personnelle, tels que les compositions de laque capillaire, notamment comme phase unique; les formulations à faible teneur en contaminants organiques volatils, telles que celles utilisées dans les systèmes d'aérosols; et les formulations de solvants anhydres, alcooliques, aqueuses-alcooliques et très tolérantes aux hydrocarbures. En utilisation, ces compositions de laque capillaire sèchent en formant des films transparents, continus et sans défaut.
