  • Attrition resistant catalyst system for manufacture of polyolefins
    Patent number: 9605089
    Abstract: The present invention relates to regular shaped magnesium particles containing attrition resistant precursors and procatalysts thereof and processes for their synthesis and their use in the manufacture of polyolefins. More particularly, the present invention relates to a process for the synthesis of a said precursor particles which give highly active and improved surface area procatalysts for producing high bulk density polyolefin resins containing low fines and capable of incorporating high rubber content. In particular, the present invention relates to process for the synthesis of an attrition resistant precursors to prepare an attrition resistant Zeigler Natta procatalysts synthesized by using the precursors and to the polyolefin resin synthesized using the said procatalysts.
    Type: Grant
    Filed: January 14, 2015
    Date of Patent: March 28, 2017
    Assignee: RELIANCE INDUSTRIES LIMITED
    Inventors: Virendrakumar Gupta, Saurabh Singh, Jomichan Joseph, Kamlesh J. Singala, Bhavesh K. Desai
