The plastic hairclip comprises a mount retainer, a lever retainer with a pair of releasing tabs, a hinged pivotal root and a pair of open-able jaws, which functions to accommodate, hold and release a hair bundle by intrinsic plastic resilience thereof. The plastic hairclip is made of a polymerized plastic mixture by 55% of 1,4-cyclohexanedimethanol (CHDM), 30% of ethylene glycol (EG), 10% of phosphotungstic acid (PTA), 1% of optical brightener and 4% of polypropylene (PP) or butadiene-styrene copolymers sold under the trademark, K-Resin with 5% tolerance for each individual component respectively. Thereby, the plastic hairclip product features in good malleability, re-plasticization ability and tenacity as well as good artistic effect in shining brightness and eco-friendly effect.

  • Patent number: 8088490
    Abstract: A halogen-free varnish includes (A) resin, (B) curing agent, (C) flame inhibitor (flame-retarding agent), (D) accelerator and (E) additives. Resin of (A) has novolac epoxy resin, DOPO-CNE and DOPO-HQ-CNE. Curing agent of (B) includes Benzoxazine resin and phenol novolac resin. Glass fabric cloth is dipped into the halogen-free varnish so as to form a prepreg with better thermal stability, anti-flammability, low absorbent ability and higher curing rate. Furthermore, the prepreg has more toughness.

  • Patent number: 8013065
    Abstract: A method for making a multi-branched polymer includes reacting a first polymeric unit with a functional cyclic compound to form a functional macroinitiator compound with a cyclic moiety. The functional macroinitiator compound is reacted with an amine functional compound to open the cyclic moiety and form a first functional group and a second functional group. To form the branched polymer, at least one of a second polymeric unit is propagated from the first functional group and a third polymeric unit is propagated from the second functional group.

  • Patent number: 8013078
    Abstract: This invention is related to heteroatom containing diamondoids (i.e., “heterodiamondoids”) which are compounds having a diamondoid nucleus in which one or more of the diamondoid nucleus carbons has been substitutionally replaced with a noncarbon atom. These heteroatom substituents impart desirable properties to the diamondoid. In addition, the heterodiamondoids are functionalized affording compounds carrying one or more functional groups covalently pendant therefrom. This invention is further related to polymerizable functionalized heterodiamondoids. In a preferred aspect of this invention the diamondoid nuclei are triamantane and higher diamondoid nuclei. In another preferred aspect, the heteroatoms are selected to give rise to diamondoid materials which can serve as n- and p-type materials in electronic devices can serve as optically active materials.
