  • Patent number: 4703068
    Abstract: Disclosed is a method of making a cross-linked poly(dicyclopentadiene) with a metathesis-catalyst system, where the metathesis-catalyst system contains an organoaluminum or organoaluminum halide activator and a pentavalent tantalum catalyst. In a preferred embodiment, the cross-linked polymer is formed by combining, in a first place, a plurality of reactant streams, one reactant stream which contains the activator, a second reactant stream which contains the catalyst and at least one reactant stream which contains dicyclopentadiene; then injecting the combined reactant streams into a second place, such as a mold, where polymerization occurs. Use of the pentavalent tantalum catalyst results in the formation of a cross-linked polymer having less color and greater transparency than cross-linked poly(dicyclopentadiene) made without a pentavalent tantalum catalyst.

  • Patent number: 4632912
    Abstract: Ziegler-Natta catalysts which are polymer supported compounds or complexes of elements of the d-block transition metals, lanthanide or actinide series are disclosed. An example of the polymer support is chloromethylated polystyrene-divinyl benzene copolymer covalently bonded to catechol. An example of the compound or complex of an element of the transition metal, lanthanide or actinide series is that which results when catechol which is covalently bonded to the polymer is contacted with titanium tetraisopropoxide. These catalysts are useful in preparing polymers with reduced halide content which reduces corrosion in polymer processing equipment.

  • Patent number: 4629771
    Abstract: A suspension which comprises an inert liquid medium, a solid material, a transition metal compound and an agglomeration aid is dried using a spray-drying technique. The spray-drying is effected under conditions of temperature and pressure which are such as to cause evaporation of the liquid medium. The solid material is preferably in a finely-divided form and may consist essentially of a transition metal compound or may be a transition metal compound which is supported on a suitable solid inert matrix material. Alternatively, a suspension of a solid support material in a solution of a transition metal compound may be used. The agglomeration aid may be polystyrene dissolved in the inert liquid medium. The dried solid is obtained as an agglomerated solid which can be mixed with an organic compound of a non-transition metal to give an olefin polymerization catalyst system.

    Abstract: A process for producing .alpha.-olefin polymers is proposed wherein the catalyst prepared and used therein is superior in the shelf stability and heat stability. The process comprises reacting TiCl.sub.4 with a reaction product (I) of an organoaluminum compound with an electron donor to obtain a solid product (II), which is then subjected to polymerization treatment with an .alpha.-olefin, and further reacted with an electron donor and an electron acceptor to obtain a solid product (III), which is then combined with an organoaluminum compound, to obtain a catalyst, in the presence of which .alpha.-olefin(s) are polymerized. The catalyst can be further preactivated with an .alpha.-olefin in advance of its use for the polymerization.
