Clayton B. Quinn 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).

  • Preparation of dichloroketene-ketals
    Patent number: 4102934
    Abstract: Dichloroketene-ketals can be made by the reaction of tetrachloroethylene with an alkali-metal phenate. The latter compounds can be converted to corresponding dihydroxy derivatives which can be phosgenated to make polycarbonate resins useful in the molding and coating arts.
    Type: Grant
    Filed: April 20, 1977
    Date of Patent: July 25, 1978
    Assignee: General Electric Company
    Inventor: Clayton B. Quinn
  • Preparation of dichloroethylene polymers
    Patent number: 4073774
    Abstract: Dichloroethylene polymers can be made by the reaction of tetrachloroethylene with a dialkali-metal salt of bisphenol-A. The latter polymers are useful in the molding and coating arts.
    Type: Grant
    Filed: April 20, 1977
    Date of Patent: February 14, 1978
    Assignee: General Electric Company
    Inventor: Clayton B. Quinn
  • Dehydrochlorination method
    Patent number: 4073814
    Abstract: A method is provided for dehydrochlorinating 1,1,1-trichloro-2,2-bis(4-hydroxyphenyl)ethane to produce substantially pure 1,1-dichloro-2,2-bis(4-hydroxyphenyl)ethylene, based on the employment of a dipolar aprotic solvent and a basic alkali metal compound, such as sodium hydroxide, sodium carbonate, etc. Crystallization of the 1,1-bis(p-hydroxyphenyl)-2,2-dichloroethylene from the dehydrochlorination reaction mixture can provide monomer useful for making high impact, flame retardant thermoplastic polycarbonates.
    Type: Grant

  • Novel polyetherimides
    Patent number: 3968083
    Abstract: This invention is concerned with a new class of polyetherimides. More particularly, the invention is concerned with polyetherimides derived from the reaction of an organic diamine and a class of dianhydrides selected from the class consisting of a bisphenol fluorenone dianhydride and a phenolphthalein dianhydride.
    Type: Grant
    Filed: February 27, 1975
    Date of Patent: July 6, 1976
    Assignee: General Electric Company
    Inventor: Clayton B. Quinn
  • Dianhydrides of bis-(orthodicarboxyphenyloxyphenyl)acetylene and bis-(ortho-dicarboxyphenyloxyphenyl)2,2-dichloroethylene
    Patent number: 3956322
    Abstract: The invention is concerned with dianhydrides derived from either tolane or 1,1-bis(p-hydroxyphenyl)2,2-dichloroethylene. These dianhydrides can be reacted with organic diamines to form polyetherimides useful in the molding art.
    Type: Grant

    Assignee: General Electric Company
    Inventors: Clayton B. Quinn, Frank J. Williams
  • Novel polyetherimides prepared from tolane dianhydride or dichloroethylene diphenylene dianhydride
    Patent number: 3944517
    Abstract: This invention is concerned with polyetherimides derived from the reaction of an organic diamine and a dianhydride selected from the class consisting of a tolane dianhydride and a dichloroethylene diphenylene dianhydride.
    Type: Grant
    Filed: March 14, 1975
    Date of Patent: March 16, 1976
