| abstract | OLEFIN POLYMERIZATION PROCESS AND CATALYST Abstract of the Disclosure Supported, chemically-modified, transition metal chloride com-pounds are prepared by a multistep process in which: (1) A finely divided polymer such as polyethylene is suspended in an alkanol solution of a magnesium com-pound, e.g. a solution of magnesium chloride in methanol, (2) The alkanol is vaporized to deposit a magnesium compound-alkanol complex on the support, (3) The product of Step (2) is suspended in a hydrocarbon and reacted with an aluminum alkyl compound such as diethyl aluminum chloride, and (4) The product of Step (3) is reacted with a transition metal chloride compound such as titanium tetrachloride. The products as thus prepared are reacted with aluminum alkyls such as triethyl aluminum to prepare catalysts useful in the polymerization of ethylene. |
