    Energy saving material launch with Mitsubishi Chemical???

    United States Patent Application 20130143994
    Kind Code A1
    VAN HARTINGSVELDT; Edwin Adriaan Andre ; et al. June 6, 2013

    [0021] The metal compound b) is capable of being activated by electromagnetic radiation and thereby forming elemental metal nuclei within the polycarbonate composition. The component b) capable of being activated by radiation is comprised of electrically non-conductive high-thermal-stability organic or inorganic metal compounds which are preferably insoluble and stable in aqueous acidic or alkaline metalizing baths. Particularly suitable compounds are those which absorb a very large proportion of the light at the wavelength of the incident light. Compounds of this type are described in EP-A-1 274 288. Preference is given here to compounds of metals of the d and f group of the Periodic Table of the Elements with non-metals. The metal-containing compounds are particularly preferably metal oxides, in particular oxides of the d-metals of the Periodic Table of the Elements. Higher metal oxides which contain at least two different kinds of cations and have a spinel structure ........... Copper oxides of the formula CuO or Cu.sub.20 are also particularly suitable, and use is preferably made here of nanoparticles, such as NANOARC(R) Copper Oxide from Nanophase Technologies Corporation, Illinois, USA. In another particularly preferred embodiment of the invention, the higher spinel oxide is a manganese-containing spinel.

    [0032] It has surprisingly been found that the presence of a rubber like polymer in an amount of at least 2.5 mass % in aromatic polycarbonate compositions comprising a metal compound capable of being activated by electromagnetic radiation and thereby forming elemental metal nuclei, results in less degradation or even prevents the degradation of the polycarbonate in the composition, as for example manifested in an increase of melt flow stability...

    • Had a phd look over the patent and the nano arc copper is vital to the patent. He says the shape of the particle makes it work. We are still not sure of the true application yet tho.

    • What makes think nanx is involved with Mitsubishi?
