Patents by Inventor John V. Bailey

John V. Bailey 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).

  • Stabilized polycarbonates
    Patent number: 4816504
    Abstract: Polycarbonate compositions comprising a small amount of a certain halogenobenzotriazole were found to be particularly suitable for optical purposes since they feature a desirable high UV-cutoff and since they are processable at high temperatures.
    Type: Grant
    Filed: October 13, 1987
    Date of Patent: March 28, 1989
    Assignee: Mobay Corporation
    Inventors: John V. Bailey, Sivaram Krishnan
  • Stabilized polycarbonates
    Patent number: 4097547
    Abstract: Halogenated polycarbonate polymeric materials containing an effective amount of barium carbonate, strontium carbonate and/or calcium carbonate to stabilize the polymer.
    Type: Grant
    Filed: December 26, 1972
    Date of Patent: June 27, 1978
    Assignee: Mobay Chemical Corporation
    Inventors: Thomas H. Cleveland, John V. Bailey
  • Pigmented polycarbonates
    Patent number: 4049614
    Abstract: Polycarbonates are pigmented with an opaque pigment such as TiO.sub.2 and contain, intimately mixed therein, a silica at a level of 0.01 to 3% by weight. The silicas are those produced by the flame hydrolysis of SiCl.sub.4 and have a particle size up to about 10 microns. The pigmented polycarbonates can be moulded to form articles having excellent surface appearance and are especially adapted for moulding polycarbonates in moulds having radical contours and fine interstices which constrict the flow path of the polycarbonate during moulding.
    Type: Grant
    Filed: October 22, 1976
    Date of Patent: September 20, 1977
    Assignee: Mobay Chemical Corporation
    Inventors: Arthur L. Baron, John V. Bailey
  • Ternary polyblends prepared from polybutylene terephthalates, polyurethanes and aromatic polycarbonates
    Patent number: 4034016
    Abstract: Ternary polyblends consisting essentially of polybutylene terephthalates, polyurethanes, and aromatic polycarbonates in proportions within carefully delineated ranges exhibit solvent stress cracking resistance and a toughness not to be found in any one or blended two of the foregoing components.
    Type: Grant
    Filed: July 15, 1976
    Date of Patent: July 5, 1977
    Assignee: Mobay Chemical Corporation
    Inventors: Arthur L. Baron, John V. Bailey
  • Utilization of bisphenol-A from the alkaline phase generated in the production of polycarbonates
    Patent number: 4025489
    Abstract: This invention relates to polycarbonates and more particularly to recovering unreacted bisphenol-A from the alkaline phase generated in the production of polycarbonates, comprising reacting the alkaline phase with phosgene to convert the unreacted bisphenol-A to a low molecular weight polymer and returning a solvent solution of the low molecular weight polymer to the main reaction stream.
