To a degassed solution of maleic anhydride (24.2 g, 0.247 mol) in chlorobenzene (400 ml) is added an equimolar amount of styrene (25.7 g, 0.247 mol) and with azodiisobutyronitrile initiator at 1 mol %, and the solution is stirred for about 18 hours at 60° C. The resultant polymer product slurry is poured into hexane, and the polymer is recovered by filtration. Purification is accomplished by reprecipitation of tetrahydrofuran solution of the polymer into toluene.
