Publication number: 20160002372Abstract: 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.Type: ApplicationFiled: January 22, 2014Publication date: January 7, 2016Inventors: Priyanshu Bharatkumar VYAS, Harshad Ramdas PATIL, Virendra Kumar GUPTA
