Abstract

The invention disclosed novel amino functional silicone polymers which have an ether amino pendant group. Compounds of the invention by virtue of their ether amino group, deposition on the surface of substrates, either alone or as complexes with cations, thereby altering the substrate's surface physical properties. The desirable durable properties which can be given to substrates include: softness, lubrication, soil release, and hydrophobicity. The compounds of the present invention are prepared by introduction of an amino group onto the silicone pendant group. Cyanoethylation followed by hydrogenation or reaction with ethylenimine or propylenimine of a hydroxy containing silicone polymer, or hydroxy containing vinyl intermediate which is subsequently introduced into the polymer backbone by hydrosilation are the preferred methods of preparation.
