  • Patent number: 7790798
    Abstract: Methods are provided for making solution masterbatches containing a diene elastomer in an organic solvent and a silica filler, having a first average particle size, that is ground in an organic solvent to form a silica having a reduced second average particle size. Grinding of the silica in the organic solvent, with or without other ingredients including the elastomer, produces a solution masterbatch in which the silica is mixed with and well dispersed in the elastomer. The use of such desolventized solution masterbatches in vulcanizable rubber compounds results in excellent processing characteristics allowing for the reduced use of processing aids such as oil. The compound also demonstrates improved properties, including reduced hysteresis.

  • Patent number: 7776943
    Abstract: A method for forming a nanocomposite by olefin polymerization in which at least one cation-exchanging layered load material, selected from the group consisting of cation-exchanging, layered inorganic silicates and cation-exchanging, layered compounds other than silicates, is treated with acid to disrupt its layered structure and is combined with a catalyst that becomes activated for olefin polymerization when in contact with the acid-treated filler. An olefin is contacted by the activated catalyst—filler combination either (a) in the absence of an alkylaluminum co-catalyst or (b) with an alkylaluminum co-catalyst when the activatable catalyst is a polyalkylmetal compound, to form a nanocomposite containing polyolefin and the acid-treated filler. In a particular embodiment, sufficient filler is used to constitute at least 30 weight % of the nanocomposite to prepare a highly loaded nanocomposite masterbatch.

    Abstract: Elastomer masterbatch is processed in a continuous compounder having multiple parallel elongate rotors axially oriented in an elongate processing chamber. Optionally, additional materials are compounded into the masterbatch, e.g., additives, other elastomeric compositions, etc. Preferably, the masterbatch then is further processed in an open mill. Excellent control of Mooney Viscosity is achieved. In certain preferred embodiments, elastomer composites are produced by novel continuous flow methods and apparatus in which fluid streams of particulate filler and elastomer latex are fed to the mixing zone of a coagulum reactor to form a coagulated mixture in semi-confined flow continuously from the mixing zone through a coagulum zone to a discharge end of the reactor.
