Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
39 words
An electroconductive polymer composition having improved tack properties which contains from 90 to 99.9 percent by weight of a water-soluble cationic quaternary ammonium electroconductive polymer and from 0.1 to 10 percent by weight of the polymer composition of dimethylpolysiloxane.
Claim 2
Dependent Claim
39 words
An electroconductive polymer composition having improved tack properties which contains from 90 to 99.9 percent by weight of a water-soluble cationic quaternary ammonium electroconductive polymer and from 0.1 to 10 percent by weight of the polymer composition of dimethylpolysiloxane.
Claim 3
Dependent Claim
75 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-(diallyldimethylammonium chloride), a copolymer of diallyldimethylammonium chloride and diacetone acrylamide or N-methylolacrylamide, polyvinylbenzyl trimethyl ammonium chloride, polymethacryloyloxyethyl trimethyl ammonium chloride, polymethacryloyloxyethyl trimethyl ammonium methosulfate, polyepichlorohydrin quaternized with trimethylamine or dimethylamine, copolymers of acrylamide and methacryloyloxyethyl trimethyl ammonium chloride containing from 90 to 99.5 percent methacryloyloxyethyl monomer, and poly(methacryloyloxyethyl dimethyl hydroxyethyl ammonium chloride).
Claim 4
Dependent Claim
52 words
An electroconductive polymer formulation having improved tack properties which contains from 5 to 95 percent by weight of a water-soluble cationic quaternary ammonium electroconductive polymer, 5 to 80 percent by weight of one or more binders, 5 to 95 percent of one or more pigments, and 0.1 to 10 percent of dimethylpolysiloxane.
Claim 5
Dependent Claim
52 words
An electroconductive polymer formulation having improved tack properties which contains from 5 to 95 percent by weight of a water-soluble cationic quaternary ammonium electroconductive polymer, 5 to 80 percent by weight of one or more binders, 5 to 95 percent of one or more pigments, and 0.1 to 10 percent of dimethylpolysiloxane.
