  • Patent number: 11718629
    Abstract: This invention outlines a method for synthesizing a blended resin system in a one pot reaction that may utilize, for example, bio-based anhydrosugars such as isosorbide as a principle component to produce isosorbide dimethacrylate and other monomeric materials for thermosetting applications. This invention establishes a one-pot procedure for reacting a hydroxy group containing compound with methacrylic anhydride in the first step and using the by-product methacrylic acid to react with glycidyl ethers to form additional methacrylate compounds in the second step. This methodology can be formulated to produce a wide array of resin systems that have controlled ratios of hydroxy group containing compound/cross-linker/reactive diluent. Additionally, the novel resin systems may be partially to fully bio-based, promoting global sustainability and reducing costs, and when free radically polymerized have properties that meet or exceed their petroleum derived counterparts.

  • Patent number: 11629220
    Abstract: 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.

  • Patent number: 10428175
    Abstract: Grafted triglycerides comprising a triglyceride grafted with a fatty acid residue containing 4 to 30 carbon atoms are reacted with an epoxide resin and an amine curing agent to yield an epoxy thermoset. The grafted triglyceride is prepared by reaction of an epoxidized triglyceride with a fatty acid. By varying the length of the fatty residue, the number of fatty residues per triglyceride, the identity of the epoxy resin and the amine curing agent, it is possible to prepare epoxy thermosets that exhibit superior physical properties compared to the properties of epoxy thermosets prepared without the grafted triglyceride, or as compared to epoxy thermosets wherein the epoxidized triglyceride is used in place of the grafted triglyceride.

  • Patent number: 10253135
    Abstract: Grafted triglycerides prepared from an epoxidized triglyceride and an acid anhydride containing 4 to 40 carbon atoms are reacted with an epoxy resin and an anhydride curing agent to yield an epoxy thermoset. By varying the length of fatty residues on the grafted triglyceride, the number of fatty residues per triglyceride, the identity of the epoxy resin and the anhydride curing agent, it is possible to prepare epoxy thermosets that exhibit superior physical properties compared to the properties of epoxy thermosets prepared without the grafted triglyceride, or as compared to epoxy thermosets wherein the epoxidized triglyceride is used in place of the grafted triglyceride. A significant improvement in fracture toughness with a minimal reduction of glass transition temperature may be thus achieved.

  • Patent number: 9884944
    Abstract: Functionalized polymer matrix and/or reinforcement materials that are capable of a thermoreversible Diels-Alder reaction are useful for making composite materials. Also disclosed is a composite material which includes one or both of functionalized reinforcement materials and functionalized polymer matrix materials, as well as a method for repairing a composite material including the step of thermally treating the composite material at a temperature sufficient to react a functionality on one of the reinforcement material and the polymer matrix material with another functionality via a Diels-Alder reaction. A method of making a composite material including functionalizing one or both of a reinforcing material and a polymer matrix material with a first reactive group, providing a second reactive group capable of undergoing a Diels-Alder reaction with the first reactive group and reacting the first and second reactive groups to form a composite material, is also described.
