Embodiment Construction

[0086] All of the following examples were carried out under argon atmosphere with pre-drying of the used solvents by reaction with sodium followed by distillation or passing through 3 Angstrom molecular sieves while flushing with argon.

[0087] All the metallocene complexes synthesized below are at 22°C in d 8 - Passed at 300MHz using a "Bruker DRX 300" spectrometer in THF 1 The analysis was carried out by H NMR and, furthermore, for the hydroboration complexes according to the present invention, by the X-ray diffraction technique described in Additional Annex 1.

[0088] The microstructure of each copolymer obtained in these examples was obtained by 1 H NMR and 13 C NMR technique determination. For this, a "Bruker DRX 400" spectrometer was used at 400 MHz for 1 H NMR technique at 100.6MHz for 13 C NMR techniques. Spectra were collected at a temperature of 363K using a 5 mm "QNP" probe. A tetrachloroethylene / perdeuterated benzene mixture (2:1 by volume) was used as sol...
