Procedure

A terpolymer containing 65.6 percent ethylene, 32 percent vinyl acetate, and 2.4 percent maleic anhydride, and displaying a melt index of 125 g./10 min. was prepared at the rate of 0.63 kg./hr. in a continuous 0.72-liter stirred autoclave by the following procedure. Monomers were mixed, pressured to 1900 kg./sq. cm. and fed at these rates:
