    摘要: Transparent and colorable elastomeric compositions are provided. The transparent elastomeric compositions can be covulcanized with rubbers such as polybutadiene, polyisoprene, styrene-butadiene rubber, styrene-isoprene-butadiene rubber, isoprene-butadiene rubber, ethylene-propylene diene rubber or natural rubber and a processing aid. The colorable rubber compositions have sufficient properties to function as a reinforcing member in a shoe sole or automobile tire. Preferably, both the transparent and colorable elastomeric compositions include at least one copolymer of a C4 to C7 isoolefin and a para-alkylstyrene, silica and a high cis-polybutadiene rubber.

    摘要: The present invention includes elastomeric compositions of BIMS elastomers suitable for abrasion resistant, high traction and/or air barrier articles. The compositions and articles made from those compositions of the invention can be described in any number of embodiments. In one embodiment, the composition suitable for an abrasion resistant article includes from 5 to 100 phr of a terpolymer of C4 to C7 isoolefin derived units, p-alkylstyrene derived units and p-bromomethylstyrene derived units; at least one filler such as carbon black, silica, precipitated silica, clay, or combinations thereof, and from 0.1 to 3 phr of at least one thiourea. The composition can also include from 5 to 80 phr of at least one elastomer selected from natural rubbers, polyisoprene rubber, styrene butadiene rubber (SBR), polybutadiene rubber, isoprene butadiene rubber (IBR), styrene-isoprene-butadiene rubber (SIBR), butyl rubber, halogenated butyl rubber, butadiene-acrylonitrile-styrene rubber (SNBR), and mixtures thereof. The composition can be cured by using one or a combination of curatives known in the rubber industry. For example, the composition may include from 0.1 to 10 phr of at least one of a peroxide, sulfur, a metal oxide, or a combination thereof. In a further embodiment, the thiourea is present from 0.2 to 1.5 phr in the composition.

    摘要: The present invention includes compositions suitable for air barriers such as innerliners where adhesion to tire carcass materials (e.g., SBR) and flexibility are desirable, as well as low air permeability. The invention includes a tire innerliner made by combining a filler; a sulfur cure system; optionally at least one secondary rubber; and at least one halogenated terpolymer of C4 to C8 isoolefin derived units, C4 to C14 multiolefin derived units, and p-alkylstyrene derived units. Examples of suitable fillers include modified carbon black, carbon black, silica, exfoliated clays, and combinations thereof. The present invention also includes a method of producing an elastomeric terpolymer composition comprising combining in a diluent C4 to C8 isoolefin monomers, C4 to C14 multiolefin monomers, and p-alkylstyrene monomers in the presence of a Lewis acid and at least one initiator to produce the terpolymer. Examples of suitable initiators include cumyl compounds and or halogenated organic compounds, especially secondary or tertiary halogenated compounds such as, for example, t-butylchloride, 2-acetyl-2-phenylpropane (cumyl acetate), 2-methoxy-2-phenyl propane (cumylmethyl-ether), 1,4-di(2-methoxy-2-propyl)benzene (di(cumylmethyl ether)); the cumyl halides, particularly the chlorides, such as, for example 2-chloro-2-phenylpropane, cumyl chloride (1-chloro-1-methylethyl)benzene), 1,4-di(2-chloro-2-propyl)benzene (di(cumylchloride)), and 1,3,5-tri(2-chloro-2-propyl)benzene (tri(cumylchloride)); the aliphatic halides, particularly the chlorides, such as, for example, 2-chloro-2,4,4-trimethylpentane (TMPCl), and 2-bromo-2,4,4-trimethylpentane (TMPBr).
