Procedure
In a four-neck flask provided with a stirrer, a thermometer, a condenser, a dropping funnel, and a nitrogen gas inlet, 111.6 g of isoparaffin solvent (produced by Exxon Chemical K.K. and marketed under trademark designation of "Isobar M") was placed and 22.3 g of sorbitan monooleate was dissolved therein. The resultant solution was emulsified by gradual addition thereto of a mixed solution prepared as an aqueous monomer solution by combining 167 g of the hydrochloride of aminoethyl methacrylate obtained by the reaction of methacrylic acid and ethylene imine, 33 g of acrylic acid, and 135 g of deionized waterl. The emulsion in the flask, with the interior of the system thoroughly displaced with nitrogen and heated to 60° C., and 0.4 g of 2,2'-azobis(dimethyl valeronitrile) added thereto as a catalyst were heated at 60° C. and stirred for 8 hours, to produce an additive M for the production of paper according with the present invention.
