摘要： Polyacrylate esters with quaternary ammonium groups are disclosed. The esters are obtained by transesterifying alkyl polyacrylate esters with dialkylaminoalkanols, 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.

The organopolysiloxane B is a linear siloxane containing quaternary ammonium groups with at least 20 dialkylsiloxy units, to which at least 2 quaternary ammonium groups are linked over carbon atoms, the ratio of the number of dialkylsiloxy units to the number of quaternary ammonium groups being greater than or equal to 10. The remainder of the preparation comprises water or a water miscible solvent.The preparation improves the handle of the finished fibers or fiber products while, at the same time, hydrophilizing them. This improvement in handle is also achieved with firmly twisted, open-end yarns. The finished fibers or fiber products can be redyed or overdyed without difficulty. They have good antielectrostatic properties.
