Non-skid agent and size medicine null for paper

摘要

PURPOSE: To obtain the subject treating agent excellent in effect of preventing slip of paper surface and paper sizing property by subjecting a specific water- insoluble monomer to emulsion polymerization with a radical polymerization initiator using a specific cationic water-soluble polymer as a protective colloid. ;CONSTITUTION: (B) A water-insoluble monomer such as styrene or methyl methacrylate is subjected to emulsion polymerization with a radical polymerization initiator such as 2,2'-azobisamidinopropane hydrochloride using (A) at least one kind of cationic water-soluble polymer selected from A₁: polyethyleneimine, etc.; A₂: a polystyrene derivative obtained by replacing 40% (based on total styrene unit) of benzene ring by methyl group containing a quaternary ammonium salt and A₃: a polymer obtained by (co)polymerizing monomer (s) selected from vinylamine, etc., allylamine, etc., and diallyldialkylammonium chloride as a protective colloid to provide the objective slip-proof sizing agent for paper used as emulsion. As the component A₂, a polymer of formula I [(a)/(b)=(0-60)/(40-100) (molar ratio, a+b=100); (x) is chlorine, etc.] and/or formula II [(a)/(b)/(c)=(0-60)/(0-100)/(0-100) (molar ratio, a+b+c=100); (n) is 1-8; (x) is chlorine, etc.) is exemplified.;COPYRIGHT: (C)1995,JPO
