The general polymerization procedure of Examples 109 was followed using 1.25 micromoles of [(C5Me4)SiMe2 N(t-Bu)]Ti(CH3)2 and 1.87 micromoles of the Lewis acid B(C6F5)3 mixed in 2 mL of Isopar® E were used to form the catalyst. The reaction temperature was 140° C. 808 g of Isopar® E, 19.5 g of norbornene and 25 Δpsi (0.17 ΔMPa) of hydrogen were added. The ethylene pressure was 500 psig (3.55 MPa). The polymerization time was 10 minutes. 41.3 g of a random ethylene/norbornene copolymer was isolated. The melt index (I2) was 0.587. The polymer contained 2.38 weight percent norbornene as determined by 13C NMR.
