Abstract
Copolymers useful in making electroconductive paper which impart improved solvent holdout properties to the electroconductive paper, comprising monomer units of quaternary diallyldialkylammonium and a monomer of the formula: --CH.sub.2 .dbd.C(R.sub.1)--C(O)--O--R.sub.2, where R.sub.1 is hydrogen or methyl; R.sub.2 is an alkyl group of 2 to 12 carbon atoms, that number being designated n, substituted with fluorine atoms in number equal to from n to 2n; and for the quaternary diallyldialkylammonium monomer, the alkyl groups are independently selected from alkyl groups of one to 18 carbon atoms, and the counterion is an anion.
