Procedure

A solution of azobis(isobutyronitrile) in benzene was simultaneously introduced at a rate sufficient to keep the reactor temperature at 170°C. (about 0.587 g./hr. corresponding to 0.86 kg. catalyst per 1000 kg. of terpolymer). The total benzene feed was 1.04 kg./hr. The terpolymer produced was isolated by a procedure similar to that described in Procedure A. The weight percent of maleic anhydride was 1.7.
