ABSTRACT:
A transition metal composition is obtained by reacting the magnesium salt of a cycloalkyl carboxylic acid with a transition metal compound, and optionally a Lewis Base compound. The product may be used to produce an olefin polymerization catalyst by addition of for example an aluminium trialkyl and the resulting catalyst has a high activity and stereospecificity in an olefin polymerization process.
