  • Functionalized graphene oxide curable formulations
    Patent number: 11905387
    Abstract: A method of producing functionalized graphene oxide includes mixing graphene oxide with a reactive monomer containing at least one epoxy functional group and a secondary functional group that is selected from vinyl, acrylate, methacrylate, and epoxy to form a mixture, adding an activation agent, heating and stirring the mixture, cooling the mixture, separating the particles from the mixture, and drying the particles to produce functionalized graphene oxide.

  • Polyricinoleate composition and process for producing the same
    Patent number: 8729176
    Abstract: A process is disclosed wherein ricinoleic acid from petroleum alternative vegetable castor oil that has a hydroxyl group at the 12-position or a derivative thereof (an ester or a hydrogenated compound thereof) is polymerized in the presence of a synthetic zeolite and an immobilized lipase at around normal temperature without using any harmful polymerization catalysts or organic solvents which can cause environmental pollution whereby a polyester useful in the industry that has a weight average molecular weight of 20,000 or more is obtained. This high-molecular weight polyester is crosslinked to give a crosslinked elastomer that is comparable to synthetic rubbers.

  • Epoxy resin formulation containing epoxy group-terminated polyesters
    Patent number: 6489405
    Abstract: A curable epoxy resin formulation comprising a) 40 to 100% by weight of an epoxy group-terminated polyester of a dimerised or trimerised fatty acid and a polyhydric alcohol, and 0 to 60% by weight of a diepoxide which is not an epoxy group-terminated polyester, b) a hardener for epoxy resins consisting of 50 to 99% by weight of a polyoxyalkylene di- or triamine and 1 to 50% by weight of a hardener which is not a polyoxyalkyleneamine, and comprising as further optional components c) a curing accelerator, and d) customary modifiers for epoxy casting resins, with the proviso that the sum of the constituents in component a) as well as in component b) is in each case 100% by weight, is suitable for use as casting resin formulation for encapsulating electrical or electronic components.
