摘要： The present invention discloses new class of nitrogen containing external donor systems. These donor systems are used in titanium supported on magnesium dichloride pro-catalyst system for polymerization of propylene. The external donor systems of the present invention in combination with silane show the kinetics control for diester catalyst polymerization process along with stereo regularity control of product. The polypropylene produced using nitrogen containing external donor systems of the present invention have broad molecular weight distribution.

摘要： In the present disclosure, a Ziegler-Natta catalyst composition for the polymerization of olefin monomers to produce polyolefin with controlled molecular weight distribution is provided wherein said controlled molecular weight distribution ranges from narrow to broad. The desired control over the molecular weight distribution of polyolefin is accomplished by using a Ziegler-Natta catalyst composition having enhanced self-extinguishing property. In the Zeigler-Natta catalyst composition of the present disclosure, in addition to a titanium and magnesium containing pro-catalyst component, a mixture of tri-alkyl aluminum compounds as a co-catalyst mixture is used. The particular combination of tri-alkyl aluminum compounds in a pre-determined weight proportion provides desirable control over the molecular weight distribution of polyolefin.
