  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: wherein R₁ is an alkyl or cycloalkyl group containing a primary or secondary carbon atom attached to the silicon atom; R₂ and R₃ are alkyl or aryl groups; and R₄ 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.
