Cationic sizing agents for paper A b s t r a c t Cationic sizing agents for paper, obtainable by a process in which a water-soluble cationic terpolymer com- pound, built up in a chemically uniform manner, of a) 7 to 40% by weight of N,N-dimethylaminoethyl acrylate and/or methacrylate, b) 40 to 80% by weight of styrene and c) 4 to 50% by weight of acrylonitrile, the sum of components a) to c) always being 100% by weight and at least 10% of the dimethylamino groups of the terpolymer being quater- nized with monoepoxides, with the exception of epihalo- genohydrins, and the remainder being protonated, is dissolved in an aqueous medium and, in the presence of 10 to 70% by weight - based on the following monomer mixture - of this emulsifier, d) 5 to 95% by weight of acrylonitrile, meth-acrylonitrile or styrene or mixtures thereof and e) 5 to 95% by weight of acrylic acid ester and/or methacrylic acid ester with 1 to 12 C atoms in the alcohol radical -the sum of components d) and e) always being 100% by weight - are emulsified and the emulsion thus obtained is subjected to emulsion polymerization, initiated by free radicals, at temperatures of 20 to 150°C.
