Procedure

58.5 g of vinylpyrrolidone (P-6-1), 70.5 g of acrylic acid (P-6-2), and 9.0 g azobisisobutyronitrile were dissolved in propylene glycol monomethyl ether and reacted at 80° C. for 9 hours to polymerize monomers. The polymerization product was purified by precipitation from hexane to obtain 110 g of a poly(acrylic acid/vinylpyrrolidone) copolymer with an Mw of 5,600 and Mw/Mn of 1.62. This copolymer is indicated as a resin P-6.
