Abstract: - 1 - HOE 90/F 277 of the disclosure: Polymer ammonium borates and processes for their preparation Polymer ammonium borates having a molecular weight from about 5000 to about 500,000 and obtained by homopolymerization of monomers, such as, for example, diallyldialkylammonium chloride, and by copolymerization of mixtures of two monomers, such as, for example, diallyldimethylammonium chloride and diallylmethyloctylammonium chloride, having molar monomer ratios of about 0.5:0.5 to about 0.95:0.05 in the copolymer, followed, if desired, by anion exchange, and mixtures of these compounds. Polymer ammonium borates according to the invention are suitable as colorless charge-control agents in toners and developers for electrophotographic recording processes and as charge-improving agents in powders and coatings for surface coating.

Abstract: HOE 90/F 278K Polymeric ammonium compounds as charge control agents Use of polymeric ammonium salts which have a molecular weight of about 5000 to about 500,000, and are obtained by homopolymerization of monomers, such as, for example, diallyldialkylammonium chloride, or by copolymerization of mixtures of two monomers, such as, for example, diethyldimethylammonium chloride and diallylmethyloctylammonium chloride, with molar monomer ratios of about 0.5:0.5 to about 0.95:0.05 in the copolymer, and if appropriate subsequent anion exchange, individually or in combination as charge control agents in electrophotographic toners and developers which are employed for copying or duplicating masters and for printing electronically, magnetically or optically stored information or in colorproofing, and as charge control agents in powders and powder coatings.
