Claim 1
Independent Claim
128 words
A COPOLYMER OF AN ETHYLENICALLY UNSATURATED FLUOROCARBON MONOMER AND AN ETHYLENICALLY UNSATURATED ACYL HALIDE RADICAL-CONTAINING MONOMER WHICH IS SUITABLE FOR USE AS AN OIL- AND WATER-REPELLENT COATING ON A FIBROUS OR POROUS SURFACE, THE COPOLYMER HAVING A CARBON TO CARBON MAIN CHAIN AND CONTAINING RECURRING MONOVALENT PERFLUOROCARBON GROUPS CONTAINING FROM 4 TO 18 CARBON ATOMS AND RECURRING ACYL HALIDE RADICALS, AT LEAST 20 PERCENT OF THE WEIGHT OF THE POLYMER BEING CONTRIBUTED BY FLUORINE ATOM IN THE PERFLUOROCARBON GROUPS AND AT LEAST 0.2 PERCENT OF THE WEIGHT OF THE POLYMER BEING CONTRIBUTED BY ACYL HALIDE RADICALS, THE HALOGEN ATOMS OF THE ACYL HALIDE RADICALS HAVING ATOMIC WEIGHT OF LESS THAN 80, SAID COPOLYMER HAVING IMPROVED SURFACE ADHERABILITY PROPERTIES AS COMPARED TO THE HOMPOLYMER OF THE CORRESPONDING FLUOROCARBON MONOMER.
