  • Process for making filled resins
    Patent number: 8541485
    Abstract: A method of making a filled resin includes the steps of: Providing a wiped film evaporator with an internal evaporator chamber maintained under vacuum and having an internal chamber wall maintained at an elevated temperature; introducing solvent-borne particles and organic matrix into the internal chamber; and compounding the solvent-borne particles and the organic matrix in the internal evaporator chamber by forming a thin film against the internal chamber wall, the thin film including organic matrix and particles, and the vacuum conditions and elevated temperature being sufficient to remove solvent from the particles and organic matrix to provide the filled resin. Less than about 10% of the particles in the resulting filled resin are agglomerated.

  • Filled resins and method for making filled resins
    Patent number: 8487019
    Abstract: A method of making a filled resin includes providing functionalized particles; and combining and homogenously mixing the functionalized particles with an organic matrix in a vacuum kneader to provide the filled resin so that the functionalized particles comprise at least about 20% by weight of the filled resin. The step of providing functionalized particles can also include providing a feedstock of (i) untreated particles, (ii) a surface treatment agent reactive with the particles, and (iii) solvent, and directing the feedstock through a continuous reactor maintained at a temperature sufficient to react the particles with the surface treatment agent to provide the functionalized particles in less than about 4 hours; and directing the functionalized particles from the continuous reactor directly into the vacuum kneader. In another aspect, the a finished resin comprises at least about 20% by weight of functionalized particles in an organic matrix.

  • Process for the surface modification of particles
    Patent number: 8394977
    Abstract: A method for the preparation of functionalized particles includes providing a feedstock that includes particles, a surface treatment agent reactive with the particles and solvent. The feedstock is direct through a continuous hydrothermal reactor maintained at a temperature sufficient to react the particles with the surface treatment agents to thereby provide functionalized particles. The method of the invention is capable of providing the functionalized particles in less than about 4 hours.

  • Process for the surface modification of particles
    Patent number: 8318120
    Abstract: A method for the preparation of functionalized particles includes providing a feedstock made of particles, a surface treatment agent reactive with the particles, and solvent. The feedstock is exposed to microwave radiation to heat the feedstock and react the particles with the surface treatment agent to provide the functionalized particles in less than about 60 minutes.
