  • Patent number: 8846816
    Abstract: The invention relates to a process and an apparatus for the preparation of a crosslinkable rubber mixture for vehicle tires, lines, drive belts and other industrial rubber articles, which can be carried out at least semicontinuously. The present invention is based on the discovery that the experiments known from the prior art to carry out the batchwise process usually used at least partly continuously have failed in particular because of the problem that the crosslinking agents have to be mixed rapidly and homogeneously with the base mixture, also referred to as rubber base mixture, without the mixture consisting of the base mixture and the crosslinking agents heating up too strongly. According to the invention, attention was therefore focussed on reliably mixing the base mixture homogeneously with the crosslinking agents and minimizing the mixing time. A first measure for achieving the desired aim consists in first mixing the crosslinking agents with one another before they are mixed with the base mixture.

  • Patent number: 8809459
    Abstract: A method of preparing a polystyrene blend that includes combining a first polystyrene composition having a first melt flow index with a second polystyrene composition having a second melt flow index and forming a polystyrene blend, the second melt flow index being at least 2 dg/min higher that the first melt flow index. The polystyrene blend has an observed tensile strength value greater than 3% above the expected tensile strength value. The second polystyrene composition can include a recycled polystyrene material, which can include expanded polystyrene. An alternate method of preparing the polystyrene blend includes combining a polystyrene composition with a styrene monomer to form a reaction mixture, polymerizing the reaction mixture and obtaining a polystyrene blend, where the polystyrene containing composition has a melt flow index at least 2 dg/min higher than the melt flow index of the styrene monomer after it has been polymerized.

    Abstract: A method of functionalizing reclaimed elastomer material is described. The method involves subjecting particles of the reclaimed elastomer material to shear at temperatures less than 100° C. such that inter-chain bonds of the reclaimed elastomer material are cleaved wherein the particles of the reclaimed elastomer material have a size of 60 mesh or smaller. The reclaimed elastomer material can be subjected to shear in the presence of a modifier which selectively promotes the cleavage of inter-chain bonds in the reclaimed elastomer material. A functionalized reclaimed elastomer material made by a method as described above and an elastomer compound which comprises the functionalized reclaimed elastomer material are also described.
