Patent number: 11629220Abstract: The present invention relates novel furan based amine cross-linkers with improved thermomechanical and water barrier properties. The novelty of this invention is the use of aromatic, and hydrophobic aliphatic aldehydes to bridge two furfuryl amines, which yields a diamine or tetra amines with a significantly enhanced hydrophobic character. These diamine cross-linkers exhibit enhanced water barrier properties and thermomechanical properties when cured with both commercial and synthetic epoxies.Type: GrantFiled: August 21, 2018Date of Patent: April 18, 2023Assignees: Drexel Unversity, The Government of the United States of America, as represented by The Secretary of the ArmyInventors: Giuseppe R. Palmese, Santosh K. Yadav, John Vergara, John J. LaScala

Patent number: 9394427Abstract: Grafted triglycerides comprising an acrylated triglyceride grafted with a fatty acid residue containing 4 to 28 carbon atoms. Also described are methods for making a grafted triglyceride and for curing a material selected from vinyl esters and unsaturated polyesters and mixtures thereof and optionally a reactive diluent. The method includes the steps of mixing a grafted triglyceride of the present invention with a material selected from vinyl esters, unsaturated polyesters and mixtures thereof to form a mixture, and curing the mixture to form a cured resin system. A cured resin system comprising a cured product obtained by the foregoing method and composites containing the cured product and a filler or reinforcing material are also disclosed. This method also includes use of the grafted triglycerides to make toughened resin and composite systems with reduced hazardous air pollutants without significantly reducing the glass transition temperature and significantly increasing the viscosity.Type: GrantFiled: July 2, 2015Date of Patent: July 19, 2016Assignees: The United States of America as represented by the Secretary of the Army, Drexel UniversityInventors: Giuseppe R.
