  • 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

  • Patent number: 8633124
    Abstract: The invention relates to a process for the synthesis of spheroidal magnesium alkoxide having improved mechanical strength and narrow particle size distribution, the process comprising reacting magnesium metal, in the presence of iodine, with a mixture of alcohols by step-wise heating first in the range of 40° C. to 65° C. for a period of 2 hours and then in the range of 65° C. to 80° C. for a period of 1 hour, further by maintaining reaction temperature at 80° C. for a period of 6-10 hours, the vapors of the mixture produced during the reaction being condensed in an overhead condenser, hydrogen gas produced during the reaction being vented off and the mixture of alcohols left after the reaction being filtered and reused. The invention also relates to spheroidal magnesium alkoxide particles synthesized by the method, to the Ziegler natta procatalyst synthesized by using the alkoxide and to the polymer resin synthesized using the procatalyst.
