摘要:
An improved process and composition for water- and oil-proofing textiles which comprises treating a textile with a polymeric fluorocarbon finishing agent and at least one reactive polymer extender of the formula ##EQU1## and curing the treated textile at from 80.degree.C to 170.degree.C for 0.1 to 60 minutes; wherein C.sub.1 and C.sub.2 are carbon atoms of a polyalkylene copolymer chain, R and R' are hydrogen, alkyl, phenyl, --COOH or a segment of a polyalkylene chain, R.sub.1 and R.sub.2 are alkyl, aryl, aralkyl, alkaryl, or the like, of up to about 20 carbon atoms, and X is a halogen. The treatment in accordance with the present invention results in synergistic improvements in the oil- and/or water-repellent properties of the conventional fluorocarbon agents.

摘要:
Substrates or articles having surfaces with silanol-reactive groups, e.g. glassware and ceramic cookware having hydroxylic surfaces, are coated with hydrolyzable di-silyl poly(perfluorooxyalkylene) compounds to provide said substrates or articles with a durable, oil and water repellent, abrasion resistant polysiloxane coating or film.

1,4-BIS(HEPTAFLUOROISOPROPOXY)-2-BUTENE IS OXIDIZED TO FORM THE CORRESPONDING EPOXIDE
2,3-DI((CF3)2-CF-O-CH2-)OXIRANE
THIS EPOXIDE CAN BE CONVERTED INTO HOMO- OR CO-POLYMERS WHICH ARE USEFUL FOR ENHANCING THE REPELLENCY OF FIBROUS SUBSTRATES, E.G., FABRICS MADE FROM NATURAL OR SUNTHETIC FIBERS.
摘要:
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.
