Procedure

A styrene/acrylonitrile/maleic anhydride terpolymer (SAMA 1) was prepared under steady state conditions in a single reactor. Monomer feed was about 81 wt % styrene; 9 wt. % acrylonitrile and 10-11% wt % maleic anhydride. The reaction was continued until about 50% of the monomers were converted to polymer. The product was then transferred to a devolatilizer where the unreacted styrene and acrylonitrile were removed and recycled back to the reactor vessel.
