Larry A. Wendling 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).

  • Irradiation of polyacrylate films in air
    Patent number: 4323591
    Abstract: Polyacrylate materials having certain heterocyclic nuclei within the structure have been found to be readily and polymerizable by irradiation in air. Typically, polyacrylate materials are highly sensitive to the presence of oxygen and do not polymerize fully unless special precautions or conditions are undertaken.
    Type: Grant
    Filed: January 29, 1981
    Date of Patent: April 6, 1982
    Assignee: Minnesota Mining and Manufacturing Company
    Inventors: Larry A. Wendling, John B. Covington
  • Energy sensitive element having crosslinkable polyester
    Patent number: 4316952
    Abstract: Water-dispersible radiation curable polyesters having backbone hydantoin groups and alpha-methylene groups are disclosed. These polyesters are useful in the field of graphic arts.
    Type: Grant
    Filed: January 5, 1981
    Date of Patent: February 23, 1982
    Assignee: Minnesota Mining and Manufacturing Company
    Inventor: Larry A. Wendling
  • Water-dispersible energy curable heterocyclic group-containing polyesters
    Patent number: 4309529
    Abstract: Water-dispersible radiation curable polyesters having backbone hydantoin groups and alpha-methylene groups are disclosed. These polyesters are useful in the field of graphic arts.
    Type: Grant
    Filed: May 12, 1980
    Date of Patent: January 5, 1982
    Assignee: Minnesota Mining and Manufacturing Company
    Inventor: Larry A. Wendling
  • Process for polymerizing acrylic substituted hydantoins in air
    Patent number: 4306954
    Abstract: Acrylic substituted heterocyclic compounds have been found to be curable to a non-tacky state by radiation within the ultraviolet and visible regions of the electromagnetic spectrum.
    Type: Grant
    Filed: June 25, 1979
    Date of Patent: December 22, 1981
    Assignee: Minnesota Mining and Manufacturing Company
    Inventors: Larry A. Wendling, John B. Covington
  • Poly(ethylenically unsaturated alkoxy) heterocyclic protective coatings
    Patent number: 4262072
    Abstract: Abrasion resistant coatings are comprised of a crosslinked polymeric coating comprising at least 15% by weight of said polymer derived from a polyacrylate material having a heterocyclic nucleus therein.
    Type: Grant
    Filed: June 25, 1979
    Date of Patent: April 14, 1981
    Assignee: Minnesota Mining and Manufacturing Company
    Inventors: Larry A. Wendling, John B. Covington
  • Poly(ethylenically unsaturated alkoxy) heterocyclic compounds
    Patent number: 4249011
    Abstract: Ethylenically unsaturated crosslinking agents and polymerizable monomers are disclosed. These agents contain a heterocyclic nucleus and are capable of forming oxygen insensitive, radiation curable systems.
