PCT No. PCT/JP80/00142 Sec. 371 Date Jan. 20, 1982 Sec. 102(e) Date Jan. 20, 1982 PCT Filed Jun. 24, 1980 PCT Pub. No. WO82/00038 PCT Pub. Date Jan. 7, 1982.A cellulose treating agent obtained by dispersing an alkyl ketene dimer in water in the presence of a dispersing agent comprising a reaction product of a polyalkylenepolyamine and a mixture of carboxylic acids containing at least 20% by weight of aliphatic monohydroxymonocarboxylic acids having 9 to 32 carbon atoms or a product obtained by reacting epihalohydrin with said reaction product. This cellulose treating agent existing as a very stable cationic aqueous dispersion of the alkyl ketene dimer is highly effective to impart a water repellency to cellulose fibers and can be used as a well-improved reactive sizing agent for papermaking. |
