Anthonius J. M. Breed has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Polymerization of carbon monoxide and ethylenically unsaturated carboxylic acid
    Patent number: 5128438
    Abstract: Polyanhydrides are produced by reaction of unsaturated carboxylic acid of defined structure, with carbon monoxide in the presence of a catalyst composition formed from a palladium salt, a monodentate phosphorus ligand optionally mixed with bidentate phosphorus ligand, and an oxygen-containing acid having a pKa below 2.
    Type: Grant
    Filed: April 4, 1991
    Date of Patent: July 7, 1992
    Assignee: Shell Oil Company
    Inventors: Eit Drent, Anthonius J. M. Breed
  • Preparation of poly anhydride from CO/non conjugated diene/dicarboxylic acid.
    Patent number: 5116936
    Abstract: Polyesters or polyanhydrides are produced by reaction of non-conjugated dienes with diols or dicarboxylic acids, respectively, in the presence of a catalyst composition formed from a palladium compound, a monodentate phosphorus ligand optionally employed with a bidentate phosphorus ligand and a limited amount of a protonic acid having a pKa below 2, in the substantial absence of water. The polymer products are useful as constituents of sealants, adhesives and paints.
    Type: Grant
    Filed: May 23, 1991
    Date of Patent: May 26, 1992
    Assignee: Shell Oil Company
    Inventors: Eit Drent, Anthonius J. M. Breed
  • Polymerization of carbon monoxide/norbornene with P bidentate ligand
    Patent number: 5091506
    Abstract: An improved process for the production of linear alternating polymers of carbon monoxide and hydrocarbon norbornene-type compounds comprises contacting the monomers in the presence of a catalytic quantity of a catalyst composition formed from a palladium compound, the anion of a strong non-hydrohalogenic acid and a bidentate ligand of phosphorus under polymerization conditions including a polymerization temperature above 100.degree. C. In an alternate modification, lower .alpha.-olefin is included in the reaction mixture and additional polymeric products are obtained.
