    Abstract: This invention relates to compositions and methods for producing polymers of isoprene derived from renewable resources, such as isoprene produced from cultured cells that use renewable carbon sources. A starting isoprene composition, such as a bioisoprene composition, is distinguished from petroleum based isoprene by its purity profile (such as lower levels of certain C5 hydrocarbons other than isoprene, presence of certain compounds associated with the biological process for production) and the relative content of the carbon isotopes. Polymers obtained by polymerization of such starting isoprene composition according to this invention, such as a polyisoprene homopolymer or a copolymer having repeat units that are derived from isoprene, are distinguishable from isoprene containing polymers from petrochemical resources.

    Abstract: Provided is a process for making a saturated star hydrocarbon polymer. The process has the following steps: (A) hydrosilylating tetraethylene silicon with methyldichlorosilane in the presence of a hydrosilylating catalyst to form a chlorosilane dendrimer; (B) reacting the chlorosilane dendrimer with vinylmagnesium bromide in the presence of a lithium and/or organolithium initiator stepwise to build a higher generation chlorosilane dendrimer; (C) anionically polymerizing polybutadiene in the presence of a lithium and/or organolithium initiator to form living poly(butadienyl)lithium; (D) attaching the living poly(butadienyl)lithium to the higher generation dendrimer to form a star polybutadiene; and (E) hydrogenating the star polybutadiene to form the saturated star hydrocarbon polymer. There is also provided a saturated star hydrocarbon polymer made according to the above process and a polymer composition of a matrix ethylene polymer and the saturated star hydrocarbon polymer.

  • Publication number: 20120196996
    Abstract: A tapered triblock copolymer having controlled vinyl distribution, enlarged middle block with intermediate composition and microstructure, increased compatibility between its adjacent blocks, good processing characteristics and a peak average molecular weight between 25,000 and 300,000 is made by anionically polymerizing conjugated diene and monovinyl aromatic monomers, polar modifier and initiator to make a first block rich in conjugated diene, forming a second block that is a copolymer of the conjugated diene and the monovinyl aromatic monomer and which is less rich in the conjugated diene than the first block, and forming a third block that is a homopolymer of the monovinyl aromatic monomer. The first, second and third blocks comprise 30 to 60, 20 to 50 wt % and 10 to 40 wt % of the tapered triblock copolymer, respectively. The tapered triblock copolymers may be used as asphalt modifiers, adhesives, sealants, compatibilizers, reinforcing agents and impact modifiers.

  • Patent number: 8207282
    Abstract: A novel polymeric compound is provided. The polymeric compound is highly compatible with reinforcing materials. Particularly, the polymeric compound is highly miscible with inorganic reinforcing materials in the manufacture of a tire. Further provided is a novel bifunctional initiator necessary to prepare the polymeric compound. The bifunctional initiator contains amine moieties. Active ends of the polymer are modified with an alkoxysilane compound. The polymer has an improved affinity for carbon black and silica as reinforcing materials in the manufacture of a tire. Therefore, the use of the polymer can achieve desired physical properties required in a tire, e.g., high wet traction, low rolling resistance and high tread wear.

  • Publication number: 20120071603
    Abstract: An alkali metal-reacted aromatic compound which has three or more carbon atoms which are directly bonded to alkali metal atoms and aromatic rings in one molecule is used as a polymerization initiator to polymerize a monomer mixture which is contains at least one conjugated diene compound to thereby produce a radial conjugated diene polymer. Further, active ends of the polymer having active ends which is obtained by this method is made to react with a modifier which can react with the active ends to thereby produce an end-modified radial conjugated diene polymer. According to the present invention, it is possible to provide a method of production of the radial conjugated diene polymer which gives a high degree of freedom of polymer design and easy control of the polymer structure.
