ABSTRACT:
A process for improving the flame retardancy, hygroscopic, soil release and other properties of a polymer substrate is provided in which the substrate is contacted with a suitable aqueous mixture containing a water-soluble monomer and an organic halogen-containing hydrophobic carrier compound at a temperature of between about 40.degree. C. to 100.degree. C. Polymerization of the monomer is thereafter initiated by a chemical or physical initiator to form a polymer evenly disposed on the substrate. The flame retardancy, hygroscopic, soil release and other surface properties of the substrate are thereby improved. The mixture may be in the form of an emulsion wherein the hydrophobic carrier compound is emulsified by an appropriate agent. The invention also pertains to the improved substrates prepared in accordance with the present process.
