    • The effect of the positive charge of the metal atom on the activity of metallocene catalysts has been recently studied taking CGM as an example in a paper by: Guo, D.; Yang, X.; Liu, T.; Hu, Y. Macromol. Theory Simul. 2001, 10, 75. Their conclusions are in agreement with the results obtained in this work.
