  • 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: 8816003
    Abstract: This invention involves a composition, a method of making, and an application of high plasticization-resistant chemically cross-linked polymeric membranes such as cross-linked cellulose acetate (CA) membrane. These cross-linked polymeric membranes with covalently interpolymer-chain-connected rigid networks showed no decrease in CO2/CH4 ideal selectivity under 690 kPa (100 psig) pure CO2 pressure and also no CO2 plasticization up to 3447 kPa (500 psig) pure CO2 pressure. By using the method of chemical cross-linking as described in this invention, the separation characteristics of the polymeric membranes can be decisively improved. These new cross-linked polymeric membranes can be used not only for gas separations such as CO2/CH4 and CO2/N2 separations, O2/N2 separation, olefin/paraffin separations (e.g. propylene/propane separation), iso/normal paraffins separations, but also for liquid separations such as pervaporation and desalination.

  • Publication number: 20130184411
    Abstract: High strength presulfided catalyst for hydrogenating hydrocarbon resins without an in situ sulfiding step. The catalyst particles have a supported metal catalyst structure with presulfided interstitial surfaces with about 20 weight percent of a low molecular weight hydrocarbon resin, based on the weight of the porous supported metal catalyst structure, filling from 90 to 95 percent of the pore volume to improve a crush strength of the catalyst particles. The presulfided catalyst can be stored and/or shipped in an airtight container with an inert atmosphere. The catalyst particles are made by preparing the oxidized catalyst, presulfiding the catalyst, contacting the catalyst with the low molecular weight hydrocarbon resin in an inert atmosphere, sealing the catalyst in a storage/shipping container, loading the reactor with the presulfided, filled catalyst, and contacting the catalyst with an unsaturated hydrocarbon resin under hydrogenation conditions.

  • Publication number: 20130131229
    Abstract: A process for preparing graft polymers from a polymer is based on conjugated diene units and a graft which is a thiol derivative. The process has an absence of solvent and any radical initiator. The graft polymer can be advantageously be used as additive for a bitumen/polymer composition and in particular permits thermoreversible cross-linking.

  • Patent number: 8399572
    Abstract: The invention provides compositions comprising nitrogen containing chelating agents, which can be used to reduce the effects of zinc contamination on the vulcanization rates of polymercapto based cure systems for halogenated elastomers. Such chelating agents are effective at eliminating vulcanization rate inconsistencies due to zinc contamination, without inducing negative changes to the vulcanization reaction or the subsequent physical properties of the halogenated elastomer vulcanizate. The invention also provides methods of curing a halogenated elastomer using the inventive compositions, and for articles prepared from the same.
