ABSTRACT:
The present invention provides a catalyst system that exhibits unprecedented catalyst efficiencies and control of desired properties in the polymer product. The catalyst system includes a new generation titanium catalyst in combination with an electron donor described by the formula: ##STR1## wherein R.sub.1 is an alkyl or cycloalkyl group containing a primary or secondary carbon atom attached to the silicon atom; R.sub.2 and R.sub.3 are alkyl or aryl groups; and R.sub.4 is an alkyl or cycloalkyl group with a primary or secondary carbon atom attached to the silicon atom. The system has a catalyst efficiency of over 30 kg/g-cat.h as the Si/Ti mole ratio varies from 4-20 in the system. The system easily achieves efficiencies over 30 kg/g-cat.h. The system also exhibits good control over the xylene solubles of the polymer products.
