  • Tertiary alkanolamines to increase viscosity of filled liquid polymers
    Patent number: 4438235
    Abstract: Filled liquid, polyhydroxyl-containing polymers such as polyether and polyester polyols can be increased in viscosity by incorporating therein a tertiary alkanol monoamine.
    Type: Grant
    Filed: September 30, 1982
    Date of Patent: March 20, 1984
    Assignee: BASF Wyandotte Corporation
    Inventor: Bernardas Brizgys
  • Organic zirconium compounds to reduce viscosity of filled liquid polymers
    Patent number: 4423180
    Abstract: Curable compositions and a process for the preparation of a low viscosity, filled liquid polymer having active hydrogen-containing groups are disclosed. An organic zirconium compound lowers the viscosity of a combination of a liquid polymer and an inorganic filler.
    Type: Grant
    Filed: August 12, 1982
    Date of Patent: December 27, 1983
    Assignee: BASF Wyandotte Corporation
    Inventors: Bernardas Brizgys, James A. Gallagher
  • Polyurethane sealant compositions
    Patent number: 4359549
    Abstract: The subject matter of this invention pertains to polyurethane sealant compositions which are flexible, strong, and resistant to shrinkage. The sealants are prepared by reacting a mixture of polyether polyol and inorganic filler with a polyisocyanate. The polyurethane sealants are useful for making castings, for patching, and as heat barriers.

  • Zirconium and mercury compounds as co-catalysts for the preparation of noncellular polyurethanes
    Patent number: 4312971
    Abstract: The subject matter of this invention relates to the preparation of polyurethanes. It is particularly concerned with the use of certain organo-zirconium and organo-mercury compounds as co-catalysts in the preparation of polyurethanes.
    Type: Grant
    Filed: December 8, 1980
    Date of Patent: January 26, 1982
    Assignee: BASF Wyandotte Corporation
    Inventors: James A. Gallagher, Bernardas Brizgys
  • Preparation of polyurethane from a blend of polyether polyols and a graft polyol which is the product of polymerization of an ethylenically unsaturated monomer with a polyol which contains unsaturation and oxyalkylene moieties
    Patent number: 4261877
    Abstract: By using a polyether polyol grafted with a suitable proportion of a suitable vinyl-type monomer with the use of a free-radical catalyst, it is possible to obtain filled or unfilled castings of thermosetting polyurethane which has excellent physical properties as well as good processing characteristics.
    Type: Grant

    Inventors: Herwart C. Vogt, Moses Cenker, John T. Patton, Jr., Bernardas Brizgys
  • Synergistic polyurethane co-catalysts which are a combination of an organo-mercuric compound and a zinc salt of an alkyl carboxylic acid
    Patent number: 4256848
    Abstract: The reaction of an organic polyisocyanate with an organic compound containing at least 2 active hydrogen containing groups is catalyzed with a synergistic co-catalyst combination of at least one organo-mercuric catalyst and at least one zinc salt of an alkylcarboxylic acid having about 2 to about 22 carbon atoms. Useful solid (non-cellular) and foamed polyurethane products are obtained which are produced at a faster curing rate than with use of either co-catalyst alone.
    Type: Grant
