Procedure

6.34 kg/h of ethylene plus 1.06 kg/h of liquid monomers containing by weight 97.2% methyl acrylate (MA), 2.7% maleic anhydride and 0.1% butylated hydroxy toluene (BHT) as well as 0.2-0.3 kg/h of methanol as telogen were fed continuously to a 720 ml adiabatic continuous stirred tank reactor. Reaction was initiated and maintained by the addition of di(sec-butyl)peroxydicarbonate (20% PDC/80% t-butylbenzene). Reaction conditions: Reactor temperature=160° C., Feed temp.=25° C. Pressure=186 MPa, Total monomer conversion=15±1%. Comonomers were introduced into the hot reactor at appropriate reactor pressures to avoid phase separation. Approximately 6.5 kg of E/MA/maleic anhydride polymer was made with a measured composition of 46.5/51/2.5 wt % and a melt flow rate (2160 grams weight, 190° C.) of 7-9.
