    • Finely divided, cationic, aqueous polymer dispersion which is obtainable by emulsion polymerisation of ethylenically unsaturated monomers in an aqueous liquid containing a cationic prepolymer as a dispersant, wherein the cationic prepolymer is prepared in the presence of at least one polymerisation initiator by polymerisation of (a) from 15 to 45% by weight of at least one ethylenically unsaturated monomer comprising at least one quaternary ammonium group; (b) from 5 to 80% by weight of at least one optionally substituted styrene; (c) from 0 to 50% by weight of at least one C 1-12 alkyl (meth) acrylate; (d) from 0 to 10% by weight of at least one ethylenically unsaturated monomer comprising an acid group; (e) from 0 to 10% by weight of at least one ethylenically unsaturated monomer comprising an amine group; and (f) from 0 to 20% by weight of at least one non-ionic ethylenically unsaturated monomer differing from (b), (c) and (e), the sum of (a)+(b)+(c)+(d)+(e)+(f) being 100% by weight, in a first emulsion polymerisation in the presence of at least one non-ionic emulsifier, and thereafter, in the aqueous liquid containing the cationic prepolymer a second emulsion polymerisation is carried out, in the presence of at least one polymerisation initiator, of a monomer mixture comprising (i) from 10 to 70% by weight of at least one of an optionally substituted styrene or (meth) acrylonitrile; (ii) from 30 to 90% by weight of at least one CMS alkyl (meth) acrylate; (iii) from 0 to 30% by weight of at least one vinyl ester of linear or branched C1-30 carboxylic acids; and (iv) from 0 to 30% by weight of at least one non-ionic ethylenically unsaturated monomer differing from (i), (ii) and (iii), the sum of (i)+(ii)+(iii)+(iv) being 100% by weight, and the first emulsion polymerisation and/or the second emulsion polymerisation is optionally carried out in the presence of from 0 to 10% by weight of at least one polymerisation regulator. The polymer dispersions according to the present invention are suitable for use as sizing agents for paper, board and card board.

    • A vinylpyridine resin that is hardly pulverized and thermally decomposed such that the degradation of the catalytic activity is suppressed while having a pore volume and a specific surface area to maintain a sufficient catalytic activity, and also a method of manufacturing the vinylpyridine resin are provided. The resin represents: a volume ratio of the pores having a diameter of 3 through 5 nm to all the pores of not less than 4% and not more than 60%; a total pore volume of not less than 0.15 cc/g and not more than 0.35 cc/g; and a specific surface area of not less than 20 m 2 /g and not more than 100 m 2 /g. The resin can be manufactured by using a combination of a poor solvent, such as octane and not less than 50 wt% and not more than 90 wt% of a good solvent, in particular a compound having a benzene ring such as toluene, as porous agent.
    • 难以粉碎和热分解的乙烯基吡啶树脂,同时具有孔体积和比表面积以保持足够的催化活性而抑制催化活性的降解,还提供了制备乙烯基吡啶树脂的方法。 树脂表示:直径为3〜5nm的孔与全部孔的体积比为4%以上且60%以下; 总孔体积不小于0.15cc / g且不大于0.35cc / g; 比表面积不小于20m 2 / g且不大于100m 2 / g。 树脂可以通过使用不良溶剂如辛烷和不少于50重量%且不大于90重量%的良溶剂,特别是具有苯环的化合物如甲苯的多孔体来制造,作为多孔 剂。
