  • Fatty acid monomers to reduce emissions and toughen polymers
    Patent number: 8372926
    Abstract: Novel fatty acid monomers and methods for their synthesis are provided for use in polymerization reactions. Fatty acid monomers are employed as reactive diluents in the polymerization of vinyl esters and polyesters for one or more purposes selected from improving the fracture resistance, lowering the processing viscosity and reducing the volatile organic compounds present in the polymerization mixture.
    Type: Grant
    Filed: August 8, 2008
    Date of Patent: February 12, 2013
    Assignees: Drexel University, The United States of America, as represented by the Secretary of the Army
    Inventors: Guiseppe Raffaello Palmese, John Joseph LaScala, James Matthew Sands
  • Composite repair resins containing minimal hazardous air pollutants and volatile organic compound
    Patent number: 8211967
    Abstract: The present invention relates to a composition and method for fabricating composite resins that produce either reduced or zero volatile organic compound (VOC) and zero hazardous air pollutant (HAP) emissions. The non-volatile reactive diluents of the composite resin, fatty acid monomers, enhance the stability, shelf-life, flexibility and strength of the composite resin. The resins incorporating fatty acid monomers may be used to repair military equipment or for any commercial repair purposes.

  • Multi-modal vinyl ester resins
    Patent number: 7449525
    Abstract: Multi-modal vinyl ester resins having one or more of good fracture toughness, good processing viscosity, and low volatile organic compound emissions are provided. The multi-modal vinyl ester resins are the reaction product of a liquid or crystalline epoxy and an amorphous, solid epoxy, as determined at 25° C., with a vinyl carboxylic acid. The multi-modal vinyl ester resins may contain a reactive diluent, though generally, lower reactive diluent contents are required for such resins than for similar, commercially available vinyl ester resins.
