Procedure

Ethylene/1-Octene interpolymers were prepared using the general continuous solution procedure described above. Ethylene, 1-octene, and ISOPAR-E solvent were fed into the reactor at rates of about 4.50 lbs/hour, 0.70 lbs/hour, and 30.20 lbs/hour, respectively. The temperature was maintained at about 140° C., and saturated. Examples 3 and 4 were prepared by feeding Catalyst A and Catalyst B, Armeenium borate, and MMAO-3A to the reactor to produce a catalyst concentration of 2.36 ppm, a ratio of catalyst A to catalyst B of 0.44, 53.2 ppm of Armeenium borate, and 8.6 ppm of Al according to the general procedure. Other process parameters are also recorded in Table V.
