Stable aqueous polymer emulsions, production and use thereof

Stable aqueous polymer emulsions comprising the components A to C, water and, if required, further assistant and additives, component C comprising polyolefin oxidation products which have in particular carboxyl and ester groups, component D comprising aminofunctional polyorganosiloxanes and component E comprising nonionic emulsifiers, are described. The polymer emulsions preferably additionally contain condensates of fatty acids with from 5 to 150 mol %, per mole of fatty acid, of amino alcohols and with from 5 to 200 mol %, per mole of fatty acid, of polyols (component D) and at least partially quaternized condensates of fatty acids with from 0.35 to 3.5 mol, per mole of fatty acid, of tertiary amino alcohols quaternized with quaternizing agents of the formula X-R 14 , where X is a radical which can be eliminated as an anion and R 14 is a lower alkyl radical. A process for the advantageous preparation of the novel polymer emulsions and their use as assistants in permanent textile finishing, in particular as softeners and smoothing agents and for improving sewability, are furthermore described.
