  • Process for the polymerization and copolymerization of certain unsaturated hydrocarbons
    Patent number: 6365687
    Abstract: This invention relates to a process for copolymerizing unsaturated hydrocarbons of the formula CH2═CHR in which R is a saturated aliphatic radical with two or more carbon atoms or a cycloaliphatic radical, in the presence of a catalyst comprising a catalytic aluminum alkyl compound and a catalytic titanium halide compound.
    Type: Grant
    Filed: May 12, 1992
    Date of Patent: April 2, 2002
    Assignee: Basell Poliolefine S.p.A.
    Inventors: Giulio Natta, Piero Pino, Giorgio Mazzanti
  • Reducing syndiotacticity of colstyrene copolymer with base and elevated temperature
    Patent number: 5122579
    Abstract: Certain linear alternating polymers of carbon monoxide and styrene are characterized by a high degree of syndiotactic character. This degree of syndiotactic character is reduced together with an attendant increase in atactic character by contacting the syndiotactic polymer with organ base at an elevated temperature.
    Type: Grant
    Filed: July 17, 1990
    Date of Patent: June 16, 1992
    Assignee: Shell Oil Company
    Inventors: Piero Pino, deceased, Giorgia Petrucci, Marco Barsacchi
  • Removal of catalyst residues from olefin/carbon monoxide polymer with dithiocarbamate
    Patent number: 4870156
    Abstract: Catalyst residues are reduced in linear alternating polymers of carbon monoxide and at least one ethylenically unsaturated hydrocarbon produced in the presence of a Group VIII transition metal catalyst by contacting the linear alternating polymer with a dithiocarbamate compound in a non-gaseous reaction environment in an oxygenated organic reaction diluent.

  • Process for the production of 3-substituted-2,5-dioxo-tetrahydrofuran
    Patent number: 4186140
    Abstract: Process for the production of 3-substituted-2,5-dioxo-tetrahydrofuran which involves converting diketene or a substituted diketene in the presence of a catalytic quantity of a carbonyl complex or of a mixture of two carbonyl complexes of metals of the VIIIth group with carbon monoxide and hydrogen at an elevated temperature and an elevated pressure.
