Abstract

Water-insoluble graft copolymer particles are produced by graft copolymerizing, in an aqueous solution and in the presence of a free-radical polymerization initiator, 100 parts by weight of a monoethylenic unsaturated monomer, which is an ester of α-chloroacrylic acid or methacrylic acid, vinyl chloride, acrylo- or methacrylonitrile or, in particular, where appropriate, CH3- or Cl-substituted styrene, on 1-25 parts by weight of a water-soluble, cationic prepolymer which is a homo- or copolymer of an ammonium ethyl- or ammonium hydroxypropyl ester or a N-ammonium alkylamide of acrylic or methacrylic acid or a diallyl ammonium, vinylbenzyl ammonium or vinyl pyridinium compound. The prepolymer is present on the particle surface. The graft copolymer can be cross-linked or can contain cellulose-reactive groups. The graft copolymer particles are organic pigments which can be used as fillers for light-weight paper, to which they impart opacity, whiteness and smoothness without having any negative influence on the strength of the paper.
