Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 151 words
An electroconductive polymer composition containing from 90 to 99.5% by weight of a water-soluble electroconductive cationic-quarternary ammonium polymer; sufficient amounts of a stabilizer to adjust the pH to 8.0 or more, said stabilizer selected from the group consisting of potassium hydroxide, sodium hydroxide and ammonium hydroxide; and from 0.5 to 10% by weight of the polymer composition of mono- and bis-(1H,1H,2H,2H-perfluoroalkyl)phosphate esters of the formula: (C.sub.m F.sub.2m+1 C.sub.n H.sub.2n O).sub.y PO(OM).sub.3-y wherein m is an integer between 4 and 10, n is an integer between 1 and 11, y is 1 or 2 and M is a water-solubilizing cation selected from the group consisting of an alkali metal, ammonium or substituted ammonium; or ammonium bis-(N-ethyl-2-perfluoroalkylsulfonamido ethyl)phosphates, containing not more than 15% ammonium mono(N-ethyl-2-perfluoroalkylsulfonamido ethyl)phosphates, where the alkyl group is more than 95% C 8 and the salts have a fluorine content of 50.2% to 52.8% as determined on a solids basis.
Claim 2
Dependent Claim 151 words
An electroconductive polymer composition containing from 90 to 99.5% by weight of a water-soluble electroconductive cationic-quarternary ammonium polymer; sufficient amounts of a stabilizer to adjust the pH to 8.0 or more, said stabilizer selected from the group consisting of potassium hydroxide, sodium hydroxide and ammonium hydroxide; and from 0.5 to 10% by weight of the polymer composition of mono- and bis-(1H,1H,2H,2H-perfluoroalkyl)phosphate esters of the formula: (C.sub.m F.sub.2m+1 C.sub.n H.sub.2n O).sub.y PO(OM).sub.3-y wherein m is an integer between 4 and 10, n is an integer between 1 and 11, y is 1 or 2 and M is a water-solubilizing cation selected from the group consisting of an alkali metal, ammonium or substituted ammonium; or ammonium bis-(N-ethyl-2-perfluoroalkylsulfonamido ethyl)phosphates, containing not more than 15% ammonium mono(N-ethyl-2-perfluoroalkylsulfonamido ethyl)phosphates, where the alkyl group is more than 95% C 8 and the salts have a fluorine content of 50.2% to 52.8% as determined on a solids basis.
Claim 3
Dependent Claim 34 words
An electroconductive polymer composition as in claim 1 in which the water-solubilizing cation is diethanolamine and C m and C n , taken together, constitute a straight chain of at least eight carbon atoms.
Claim 4
Dependent Claim 58 words
An electroconductive polymer composition as in claim 2 in which the fluorocarbon is a member selected from the group consisting of diethanolamine salts of mono- and bis-(1H,1H,2H,2H-perfluoroalkyl)phosphates wherein the alkyl group is even numbered in the range C 8 -C 18 and the salts have a fluorine content of 52.4 to 54.4% as determined on a solids basis.
Claim 5
Dependent Claim 85 words
An electroconductive polymer composition as in claim 1 in which the cationic-quaternary ammonium polymer is a member selected from the group consisting of poly(dimethyl diallyl ammonium chloride), a copolymer of dimethyl diallyl ammonium chloride and diacetone acrylamide containing from 70 to 98% of diallyl monomer units, polyvinylbenzyl trimethylammonium chloride, polymethacryloloxyethyl trimethyl ammonium chloride, polymethacryloloxyethyl trimethyl ammonium methosulfate, polyepichlorohydrin 80 to 100% quaternized with trimethylamine, copolymers of acrylamide and methacryloloxyethyl trimethyl ammonium chloride containing from 90 to 99.5% methacryloloxyethyl monomer, and poly-(methacryloloxyethyl dimethyl hydroxyethyl ammonium chloride).
