International ClassC08G 077/00AbstractThe 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.Field of SearchMaterial contains a Group VIII metal atomSilicon reactant contains a silicon-to-hydrogen bond Organic Si-free reactant is a nitrogen-containing compound Organic Si-free reactant is a carboxylic acid or derivative Material is a metal-containing material FROM SILICON REACTANT HAVING AT LEAST ONE SILICON-TO-HYDROGEN OR -CARBON BOND Organic Si-free reactant contains a heterocyclic ring Solid polymer derived from silicon-containing reactant Silicon compound containing coating | |
