Abstract:
1. A method for determining the stoichiometric amount of alkanol to be reacted with a magnesium organic precursor compound for the preparation of a solid catalytic component of a Ziegler-Natta catalyst, the method comprising: a) providing a predetermined amount of magnesium organic precursor compound to be added to a predetermined amount of particulate solid support; b) calculating a molar equivalent amount of aliphatic or aromatic alkanol to be reacted with the magnesium organic precursor compound, the molar equivalent amount of aliphatic or aromatic alcohol being calculated according to formula: wherein Equ (mmole MgR/g support)=mmoles of magnesium organic precursor compound per gram of particulate solid support wt % (H2O)/support=weight percent of physically adsorbed water on the particulate solid support.
