1. A polyelectrolyte having an intrinsic viscosity molecular weight of at least 30,000 as determined by light scattering in 0.4M K Br consisting essentially of the adduct of linear polymeric segments of the formula:

  • ##STR16## where Z is chloro, bromo or iodo, n is an integer and x is 3 or 7 to 10 linked directly by means of the quaternization reaction between the (CH3)2 N-- or Z terminal groups of the segments to the tertiary amine or Z groups of a polyfunctional central monomer or polymeric substrate, said central monomer being selected from compounds of the formula;

    ##STR17## where Y is a polyvalent low molecular weight organic group having a valence of 3+m, m is an integer from 0-3, R3 is selected from alkylene, phenylene or alkyl ester and E is Z or (R4)3 N-- where R4 is alkyl, aryl or aralkyl and said polymeric substrates are selected from the group consisting of polyvinylpyridine, polyethyleneimine, polyvinylbenzylchloride, poly-(dialkylaminoalkyl acrylate), poly-(dialkylamino alkyl acrylamide, polyepichlorohydrin and polydialkylaminoalkylethylene oxide.
