摘要
The present invention provides a Ziegler-Natta catalyst useful in solution processes for the polymerization of olefins having a low amount of aluminum and magnesium. The catalysts of the present invention have a molar ratio of magnesium to the first aluminum component from 4.0:1 to 5.5:1 and molar ratio of magnesium to transition metal from 4.0:1 to 5.5:1.
