Electroconductive paper

Abstract

Abstract AN ELECTROCONDUCTIVE PAPER USEFUL IN MAKING COPIES BY AN ELECTROSTATIC PROCESS IS MADE BY INCORPORATING THEREIN AN N-(ALKYL AMMONIUM)ACRYLAMIDE POLYMER HAVING ABOUT 90 WEIGHT PERCENT UNITS OF THE FORMULA -CH2-C(-R6)(-CO-NH-C(-R4)(-R5)-CH(-R3)-(CH2)N- N(+)(-R1)(-R2)-RZ X(-))- WHEREIN R1 AND R2 ARE INDEPENDENTLY SELECTED FROM LINEAR AND BRANCHED ALKYL GROUPS HAVING UP TO 18 CARBON ATOMS AND ARALKYL GROUPS HAVING UP TO 10 CARBON ATOMS AND IN WHICH R1 AND R2 MAY BE COMBINED TO FORM A HETEROCYCLIC GROUP HAVING ONE OR MORE HETRO ATOMS; R2 IS SELECTED FROM THE GROUP CONSISTING OF HYDROGEN, LOWER ALKYL GROUPS OF 1 TO 4 CARBON ATOMS AND HALOGEN; R4 IS SELECTED FROM THE GROUP OF HYDROGEN, HALOGEN, AND LINEAR OR BRANCHED ALKYL GROUPS OF UP TO 5 CARBON ATOMS; R5 IS SELECTED FROM THE GROUP CONSISTING OF PHENYL, LOWER ALKYL GROUPS OF 1 TO 4 CARBON ATOMS AND SUBSTITUTED PHENYL WHEREIN THE SUBSTITUENTS MAY BE LOWER ALKYL GROUP OF 1 TO 4 CARBON ATOMS OR LOWER ALKOXY GROUPS OF 1 TO 4 CARBON ATOMS; R3 OR R4 CAN COMBINE WITH R5 TO FORM A CYCLIC GROUP OF AT LEAST 6 CARBON ATOMS OR A BICYCLIC GROUP OF AT LEAST 7 CARBON ATOMS, WHICH GROUPS CAN BE SUBSTITUTED WITH A LINEAR OR BRANCHED ALKYL GROUP HAVING UP TO 5 CARBON ATOMS; R6 IS SELECTED FROM THE GROUP CONSISTING OF HYDROGEN AND METHYL; RZ MAY BE ANY GROUP CAPABLE OF QUATERNIZING THE NITROGEN, PREFERABLY SELECTED FROM THE GROUP CONSISTING OF HYDROGEN, BENZYL, PHENETHYL, CYANOETHYL, AND LINEAR, BRANCHED AND SUBSTITUTED ALKYL AND ARALKYL GROUPS; X$ IS ANY ANION, ESPECIALLY HALIDE, ALKOSULFATE, TOSYLATE, CARBOXYLATE, SULFONATE, SULFATE, PHOSPHATE, ACETATE, NITRATE, ETC.; AND N IS AN INTEGER OF 0 TO 2.
