  • Process for the production of stereoregular polymers and elastomers of alpha-olefins and certain novel catalysts therefor
    Patent number: 6653413
    Abstract: A process for the polymerization of one or more alpha-olefins having at least 3 carbon atoms, which comprises contacting the monomer or monomers in a polar or non-polar solvent under polymerization conditions with a homogeneous catalyst system including (a) a cationic form of a racemic mixture of a chiral octahedral transition metal complex or of a non chiral octahedral transition metal complex, comprising 1, 2 or 3 bidentate chelating ligands and no cyclopentadienyl ligands and having C1, C2, or C3 symmetry; and (b) an anion of a Lewis acid or a Brönsted acid; and adjusting the pressure so as to obtain either a highly stereoregular polymer or copolymer or an elastomer.
    Type: Grant
    Filed: January 27, 2000
    Date of Patent: November 25, 2003
    Assignee: Technion Research and Development Foundation Ltd.
    Inventors: Moris Eisen, Victoria Volkis, Michal Shmulinson, Claudia Averbuj, Edith Tish
