1. A conductive composition consisting essentially of a dispersion of 20 to 95 percent by weight of a water-soluble gel forming binder polymer selected from polyvinyl alcohol or polyvinyl alcohol cross-linked to a water-insoluble and water-swellable form by reaction with a coreactive water-soluble polymer and a linear, water-soluble polyelectrolyte of the formula:
- ##STR16## where Z is chloro, bromo or iodo and n is an integer such that the intrinsic viscosity, n, as determined by light scattering in 0.4 KBr is at least 0.2 dl/g as determined by the formula;

Abstract
Cationic polyelectrolytes formed by the polymerization in absence of oxygen of a monomer of the general formula: dispersed ##STR1## where x is 3 or more than 6 and Z is I, Br or Cl to form high charge density linear polymers are dispered in a water-soluble polymer such as polyvinyl alcohol to form a conductive hydrogel.
