実験手順

In this case, the n-heptane solution of the complex consisting of di-n-butyl magnesium and tri-ethyl aluminum which was used in Example 51 was replaced with a reaction product obtained from 161 ml of an n-heptane solution of n-butyl ethyl magnesium (manufactured by Texas Alkyls Inc. of U.S.A., MAGALABEM, Mg concentration 0.65 mol/liter) and 4.3 ml of tri-ethyl aluminum. With the exception of this, a catalytic component was prepared and propylene was polymerized in exactly the same manner as in Example 1. The results of polymerization were: A=445, H.I.=94.8 and ρB=0.45.
