Participants

Reaction Steps

Polymerization was conducted in the same manner as in Example 7 except that 0.0547 MPa of hydrogen was charged, 11 mL of 1-hexene and 3 mL of 1,5-hexadiene were charged as addition polymerizable monomers instead of vinylcyclohexane, and 1.5 μmol of dimethylsilylene(tetramethylcyclopentadienyl)(3-tert-butyl-5-methyl-2-phenoxy)titanium dichloride instead of isopropylidene(cyclopentadienyl)(3-tert-butyl-5-methyl-2-phenoxy)titanium dichloride, and 7.5 μmol of dimethylaniliniumtetrakis(pentafluorophenyl) borate were used, the charging temperature was changed to 80° C. and the polymerization time was changed to 6 minutes. As a result of the polymerization, 53 g of an ethylene/1-hexene/1,5-hexadiene ternary copolymer was obtained having a melt viscosity η*190 of 1.20×103 Pa·se, a fusion heat quantity ΔH of 123 kJ/kg, a melting temperature of 113° C., and a Mw/Mn of 2.2. The resulted ethylene-based copolymer had a tensile impact strength TI of 890 kJ/m2 and a melt tension MT of 7.2 cN The results are shown in Table 5.
