    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.
