1. , successive polymerization has the method for 2-12 carbon atom α

  • alkene, this method is implemented by laxative remedy in gas-phase polymerization reactor;

    will contain and remain gaseous reaction mixture and the Ziegler-natta catalyst series of polymeric α

    alkene and contact, described catalyzer is by the solid catalyst of the compound that contains IV in a kind of periodic table of elements, V or VI group 4 transition metal at least and contain II in a kind of periodic table of elements at least or the cocatalyst of the organometallic compound of III family metal is formed, and described method is characterised in that;

    the α

    alkene is added in the polymerization reactor with constant speed.
