  • Aqueous emulsion copolymers containing lower alkyl hydrogen polysiloxane
    Patent number: 4101492
    Abstract: Aqueous emulsions adapted for application to textile fabrics and which provide improved water and soil resistance are supplied using aqueous emulsion copolymers of nonreactive monoethylenically unsaturated monomers providing a T.sub.g below about 20.degree. C. with from 0.5% to 20% of reactive monoethylenically unsaturated monomer providing active hydrogen, preferably OH and most preferably the ##STR1## AND FROM 1 TO 40% OF A TERMINAL-BLOCKED LOWER ALKYL HYDROGEN POLYSILOXANE HAVING A VISCOSITY OF FROM 20 TO 1000 CP at 20.degree. C. In preferred practice, from 0.5 to 4% of the polysiloxane is used, and at least 50% of the copolymer is vinyl acetate.
