Conditions

Temperature: 180 °C

Procedure

In an ammonia gas atmosphere, 100 parts of an isobutylene-maleic anhydride copolymer (sold under the trade name "ISOBAN 04" by KURARAY ISOPRENE K.K. of Kita-ku, Osaka, Japan) was heated to 180° C. to obtain an isobutylene-maleic imide-maleic anhydride copolymer. Then placed in a reactor were 40 parts of the isobutylene-maleic imide-maleic anhydride copolymer, 7 parts of 25% ammonia water and 160 parts of water. The mixture in the reactor was heated at 85° C. for 2 hours, thereby obtaining an aqueous solution of isobutylene-maleic imide-maleic anhydride copolymer. The aqueous solution contained 20% nonvolatile matter, and the viscosity of the aqueous solution was measured at 6,000 mPa.s.
