## Abstract Polymerization of propene at β78Β°C in the presence of a homogeneous catalytic system based on a Ni(II) diimine derivative and methylaluminoxane affords prevailingly syndiotactic crystalline poly(propylene) (rr triad content β80%). ^13^C NMR analysis of the polymer microstructure indicat

## Abstract Recently we proposed a stereochemical classification of stereorigid metallocene catalysts according to their symmetry; statistical models of increasing complexity for the polymerization of propene based on the alternating mechanism have been developed. The general model agrees with the
