    摘要: The invention relates to nanocomposites and processes for making nanocomposites comprising butyl rubber ionomers having at least 3.5 mol % of repeating units derived from a multiolefin monomer, such as isoprene. More particularly, the invention relates to butyl rubber ionomer nanocomposites comprising high aspect ratio fillers. In one preferred aspect of the invention, the nanocomposites comprise ionomers that are generated in situ during formation of the nanocomposite, leading to intercalation of the ionomer with the nanocomposite. Nanocomposites according to the present invention exhibit improved impermeability and tensile properties as compared with prior art nanocomposites made using conventional brominated butyl rubber.

    摘要: The present invention provides a process for preparing a filled halobutyl elastomer, which comprises mixing a halobutyl elastomer, mineral filler and a silazane compound or mixture of a silazane compound and an additive which contains at least one hydroxyl group and at least one substituents which bears a basic amine group, and curing the filled elastomer with sulfur or other curative systems. The present invention has the advantages of (a) not evolving alcohol either during the manufacture or subsequent use of the article manufactured from the compound, (b) improving the scorch safety of filled halobutyl elastomer compounds which employ silica as the mineral filler and a the additive containing at least one hydroxyl group and a functional group containing a basic amine as a dispersing aid and (c) significantly reducing the cost of the compound compared to analogous compounds currently known in the art.
