    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: A method to halogenate butyl rubber in the absence of water and, more particularly, without the need for addition of neutralization agents. The butyl rubber contains at least 4.1 mol% of a multi-olefin and the multi-olefin serves as a sink for the hydrohalic Brönsted acids generated when a halogenation agent is added. This obviates the need for aqueous phase acid neutralization. The novel halogenated butyl rubber produced using the method advantageously possesses a high degree of desirable exo-allylic bromides with relatively low levels of the less desirable endo-allylic bromides.

    摘要: Preparation of butyl rubber based graft co-polymers from halobutyl elastomers using phase transfer catalysts in the presence of a solution of an alkali metal salt of an oxygen or sulfur nucleophile that is bound to a polymeric substrate. Graft co-polymers can be produced of a butyl polymer (isobutene-co-isoprene) and polymeric substrates such as polyethylene, polypropylene, polystyrene, polybutadiene, polysilanes, polysiloxanes, polyethylene glycol, polyethylene oxide, polyphosphazenes, polyferrocenes or their hybrids.
