Procedure

The procedure of example 111 was followed using two consecutive additions of a catalyst solution prepared by mixing 5.0 micromoles of [C5 Me4)SiMe2N(t-Bu)]Ti(CH3)2 and 5.0 micromoles of the Lewis acid, B(C6F5)3, mixed in 2 mL of Isopar® E. The reaction temperature was 130° C. 1200 mL of a solution containing 50 mL of 5-ethylidene-2-norbornene in Isopar® E and 50 psi (0.34 ΔMPa) hydrogen were added. The ethylene pressure was 475 psig (3.38 MPa). The polymerization time was 20 minutes. 59.9 g of an ethylene/5-ethylidene-2-norbornene copolymer was isolated. The melt index, I2, was 1.55. The polymer contains 9.06 weight percent 5-ethylidene-2-norbenene as determined by 13C NMR.
