  • Patent number: 9216436
    Abstract: This disclosure concerns the production of ZnO (zinc oxide) coated particles for use in rubber as a substitute for bulk ZnO particles. Compared to bulk oxide, oxide coated particles offer the advantage of a higher specific surface per mass unit of ZnO. This implies both ecological and economical benefits. An enhanced process is presented for the synthesis of aggregate particles, comprising a core of CaCO3, which is at least partially coated with ZnO, comprising the steps of: heating a metallic Zn bath, thereby evaporating Zn and forming a Zn-vapor atmosphere; injecting CaCO3 particles as core compound in the Zn-vapor atmosphere; injecting air in the Zn-vapor atmosphere in an amount in excess of the stoechiometric need for the oxidation of the Zn vapor to ZnO. This process is clean and sustainable, producing no unnecessary phases.

  • Patent number: 8575264
    Abstract: Chain-extended nanonylon is made from the reaction of in-situ polymerized nanonylon and chain-extending agents. Knowing the viscosity/shear rate curve for a thermoplastic polymer to be replaced, such as nylon, the method of the present invention allows via adjustment of organoclay concentration and chain extension of the nylon polymer and other reaction factors to achieve a chain-extended, in-situ polymerized nanonylon to have a viscosity/shear rate curve that essentially matches the viscosity/shear rate curve for that neat nylon within a commercially operable shear rate.
