Claims
- 1. A composition for improving the water- and/or oil-repellent properties of textiles which comprises an inert anhydrous solvent containing from about 0.1 to about 10 weight percent of a polymeric fluorocarbon finishing agent, and from about 0.3 to about 10 weight percent of one or more polyalkylene copolymer extenders of the formulae ##EQU16## wherein C.sub.1 and C.sub.2 are, independently, carbon atoms of the polyalkylene chain represented by --CH.sub.2 --CH.sub.2 --.sub.n ; R and R' are, independently, hydrogen, an alkyl group of up to about 20 carbon atoms, phenyl, --COOH, or a segment of the polyalkylene chain; R.sub.1 and R.sub.2 are, independently, alkyl, aryl, aralkyl or alkaryl groups of up to about 20 carbon atoms, and X is a halogen, said polymeric extender having a molecular weight of from about 800 to about 8000.
- 2. The composition of claim 1 wherein the polymeric fluorocarbon concentration is from about 0.2 to about 3.0 weight percent.
- 3. The composition of claim 1 wherein the polymeric extender concentration is from about 0.5 to about 6 weight percent.
- 4. The composition of claim 1 wherein the solvent is perchloroethylene or 1,1,1-trichloroethane.
- 5. The composition of claim 1 wherein the molecular weight of the polymeric extender is from about 1000 to about 6000.
- 6. The composition of claim 1 wherein the polymeric extender is one or more of the following compounds
- Ethylene.sub.(45.sub.-82%) Propylene.sub.(0.sub.-40%) Acrylic Acetic Anhydride.sub.(18.sub.-25%)
- Ethylene.sub.(45.sub.-82%) Propylene.sub.(0.sub.-40%) Methacrylic Acetic Anhydride.sub.(13-25%)
- Ethylene.sub.(15.sub.-79%) Propylene.sub.(0.sub.-40%) Monoethylmaleate Maleic Acetic Anhydride.sub.(20.sub.-30%)
- Ethylene.sub.(45.sub.-82%) Propylene.sub.(0.sub.-40%) Acrylyl Chloride.sub.(10.sub.-25%).
