  • Patent number: 9932425
    Abstract: Improved reaction processes comprise reacting a mixture to form a product comprising a metal alkyl, metal oxide, or mixture thereof and then passing said product to a post-reactor heat exchanger. The improvement comprises one or more of the following: (1) reacting said metal alkyl compound with an acid to produce a soluble metal ester; or (2) adding an ionic surfactant; or (3) adding a mixture comprising an antioxidant to the product under conditions sufficient to avoid formation of significant amounts of insoluble metal or metal compounds derived from said metal alkyl compound; or (4) purging said post-reactor heat exchanger with an inert gas under conditions to remove metal oxide from the post-reactor heat exchanger.
    Type: Grant

  • Patent number: 8273838
    Abstract: Embodiments of the invention provide a class of propylene/?-olefin block interpolymers. The propylene/?-olefin interpolymers are characterized by an average block index, ABI, which is greater than zero and up to about 1.0 and a molecular weight distribution, Mw/Mn, greater than about 1.3. Preferably, the block index is from about 0.2 to about 1. In addition or alternatively, the block propylene/?-olefin interpolymer is characterized by having at least one fraction obtained by Temperature Rising Elution Fractionation (“TREF”), wherein the fraction has a block index greater than about 0.3 and up to about 1.0 and the propylene/?-olefin interpolymer has a molecular weight distribution, Mw/Mn, greater than about 1.3.
