Block and graft copolymers containing water-solvatable polar groups and fluoroaliphatic groups
Abstract
Abstract HYBRID POLYMERS PROVIDE SUFFICIENT OLEOPHOBICITY AND HYDROPHILICITY IN WATER SO THAT FABRICS TREATED THEREWITH HAVE INCREASED ABILITY TO RELEASE OILY STAINS ON LAUNDERING. OLEOPHOHIC AND HYDROPHILIC MOIETIES ARE COMBINED IN COATABLE COPOLYMERS SO THAT THE RELATIVE MOBILITY OF THE MOIETIES IS ASSURED UNDER SOME SET OF CONDITIONS OF TEMPERATURE AND ENVIROMENT. SURFACES TREATED WITH THE RESULTING COPOLYMERS RESPOND REVERSIBLY TO CHANGE OF ENVIRONMENT, E.G. GASEOUS TO AQUEOUS MILIEU AND VICE VERSA, BY A CHANGE IN KIND OF PROPERTIES. AS A NON-LIMITING EXAMPLE, FLUOROCHEMICAL MOIETIES AND HYDROPHILIC POLYTHER MOIETIES ARE COMBINED THROUGH SULFUR ATOMS TO GIVE POLYMERS WHICH A APPLIED AS OIL AND WATER-REPELLENT TREATMENTS WITH OTHER, E.G. CREASE RESISTANT, TEXTILE TREATMENTS. FRABRICS THUS TREATED ARE REPEATEDLY LAUNDERABLE TO REMOVE OILY STAINS.
