  • the sizing agents must be used in conjunction with a material which is either cationic in nature or is capable of ionizing or disassociating in such a manner to produce one or more cations or other positively charged groups.
  • the cationic agents are disclosed as "alum, aluminum chloride, long chain fatty amines, sodium aluminate, polyacrylamide, chromic sulfate, animal glue, cationic thermosetting resins, and polyamide polymers".
  • Preferred cationic agents are the various cationic starch derivates including primary, secondary, tertiary, or quaternary amine starch derivates and other cationic nitrogen substituted starch derivates, as well as cationic sulfonium and phosphonium starch derivatives. Such derivatives may be prepared from all types of starches including corn, tapioca and potato.

This composition contains two different ASA compounds and a dispersing agent which may be selected from the group consisting of cationized starch, gelatine, polyvinyl alcohol, cationic polyacrylamide and polyethyleneimine.
  • ASA sizing materials are not water soluble, and must, accordingly, be uniformly suspended in the pulp so that the size can make adequate contact with the cellulosic fibers and thus create the desired effect of the final product.
  • sizing agents which comprise 1 - 60 parts by weight of a sizing accelerating agent per 10 parts by weight of a hydrophobic sizing such as ketene dimers.
  • Useful accelerators are polymers containing primary, secondary or tertiary amino and/or quaternary ammonium groups directly bonded or present as pendant groups, such as a quaternized terpolymer which contain N,N-dimethylaminoethyl methacrylate, styrene and methyl methacrylate, acrylonitrile or n-butylacrylate units.
  • ASA sizings are not exemplified or tested. Although the molecular weight of these polymers is not specificly investigated it seems that the tested sizing accelerators are high molecular weight water-soluble polymers.

  • Tested compositions contain polyelectrolytes which have a molecular weight in the order above 10 6 .

  • the invention provides for utilization of certain specific cationic water soluble vinyl addition polymers having molecular weights of between 20,000 and 750,000 as additives and emulsifying agents for ASA sizes.

  • ASA sizes to which this invention is applicable include those mentioned in U.S. patents 3,102,061, 4,040,900, 3,968,005, and 3,821,069.
