実験手順
In a 200 ml four necked flask equipped with a stirrer, a reflux condenser and a thermometer were placed 100 g of pure water in which 0.5 g of partially saponified polyvinyl alcohol having a degree of saponification of 88% and a viscosity of its 2% aqueous solution of 23 cps and 2 g of sodium chloride had been dissolved, followed by addition of a mixture of 16.4 g of the p-diethylaminoethylstyrene as prepared in Synthesis 1, 3.6 g of divinylbenzene having a purity of 56% and a mole ratio of metaisomer to para-isomer of 7 to 3 and containing 44% by weight of ethylvinylbenzene and 0.2 g of 2,2'-azobisisobutyronitrile with stirring. Then the mixture was stirred at 60° C. for 1 hour, at 70° C. for 2 hours and further at 80° C. for 4 hours. After the reaction the reaction mixture was extracted with toluene and the amount of monomer remaining was quantitatively analyzed and found to be 1% by weight of p-diethylaminoethylstyrene based on the weight of the feed. The copolymer thus produced was spherical particles having a particle diameter of 50 to 200μ.
