  • Patent number: 8604115
    Abstract: The ethylene/propylene copolymer nanocomposite is a copolymer prepared by inclusion of a filler of nanoparticles of titania doped with iron that permits control over, and variation of, the overall polymeric properties. Through the addition of the TiO2/Fe nanofiller, the concentration of polypropylene in the copolymer is increased and the overall crystallinity is decreased. In order to make the copolymer, a TiO2/Fe titania-iron nanofiller is first mixed with a polymerization catalyst (a vanadium (III) complex bearing bidentate salicylaldiminato ligands) in a reactor. The reactor is then charged with solvent (e.g., toluene) and heated to a temperature suitable for polymerization, e.g., about 30° C. Following heating, a mixture of ethylene and propylene gases (in selected molar ratios) is fed into the reactor at a fixed pressure, and methyl aluminum dichloride co-catalyst (MADC) is added to initiate polymerization.

  • Patent number: 8232357
    Abstract: The present invention relates to a catalytic composition for producing a 1-alkene-acrylate copolymer that includes a metal nano catalyst, and a method for producing a 1-alkene-acrylate copolymer. In the catalytic composition for producing a 1-alkene-acrylate copolymer, since the content of the polar comonomer is high, it may be used to produce the 1-alkene-acrylate copolymer that has no crystallinity and is capable of being used as an optical material. The method for producing the 1-alkene-acrylate copolymer may be produced by using a simple process of a mild polymerization condition without a polymerization condition of high temperature and high pressure, and it is easy to control physical properties.
