Reaction Conditions

Reaction Steps

To a glass reaction vessel equipped with thermometer, stirrer, nitrogen gas inlet, dropping funnel and reflux condenser, are added allyl ether (manufactured by Nihon Yushi Co., Ltd.) 336 wt. parts, maleic anhydride 98.0 wt. parts, benzoyl peroxide (B.P) 6.0 wt. parts and toluene 566.0 wt. parts, and the atmosphere of the reaction vessel is replaced by nitrogen under stirring. The mixture is heated to 80° C., and allowed to react, maintaining the temperature for 4 hr. The reaction mixture is evaporated at 110° C. under reduced pressure, 10 mm Hg, to remove toluene, and brought to ordinary pressure to give an allyl ether-maleic anhydride copolymer (AMA polymer-a), Sample A(A), whose mean molecular weight by weight is 23000 (calculated in terms of PEG).
