Abstract

Polyacrylate esters with quaternary ammonium groups are disclosed. The esters are obtained by transesterifying alkyl polyacrylate esters with a mixture of dialkylaminoalkanols and saturated or unsaturated aliphatic alcohols with 8 to 22 carbon atoms, followed by quaternization. The polymers are free of physiologically questionable components and can therefore be used for the preparation of cosmetic products, preferably for hair cosmetics. The polymers furthermore are suitable for finishing fibers or of textile products. The invention is furthermore directed to polyacrylate esters with tertiary amino groups, which are formed as intermediates in the preparation of polyacrylate esters with quaternary ammonium groups.
