  • Patent number: 8063127
    Abstract: An antihazing agent for noncrystalline cycloolefin resins which can inhibit the hazing of the resins due to fine cracking caused by environmental change, particularly, environmental change from high temperature and humidity atmosphere to ordinary temperature and humidity atmosphere without losing the characteristics inherent in the resins to keep the transparency of the resins and inhibit the light transmittance thereof from lowering; noncrystalline cycloolefin resin compositions containing the agent; and optical elements made from the compositions. A compound component containing a metal rosinate as the main component is used as the antihazing agent for noncrystalline cycloolefin resins. It is particularly preferable that the antihazing agent further contain one or more members selected from the group consisting of alkali metal salts, alkaline earth metal salts, and Group 12 metal salts.

  • Patent number: 7951864
    Abstract: The present invention provides polymer nanocomposites with dispersed nanotubes and methods of making same. The polymer may be a polyether. For example, the present invention provides an effective method to successfully disperse single walled nanotubes (SWNTs) into both Polyethylenoxide (PEO) and its low molecular weight analog polyethylene glycol (PEG) with hydrodynamic percolation at about 0.09 wt % and an electrical percolation at about 0.03 wt % SWNTs at room temperature, and the resulting nanocomposites. The method may include providing a surfactant. Most notably the present inventors achieved a decrease in the melting point of the polymer and a retardation of polymer crystallization due to the presence of the nanotubes.
