Elastomeric compositions.U.S. patent: 7,241,831 Issued: July 10, 2007 Inventors: Walter Harvey Waddell and David Yen-Lun Chung Assigned: ExxonMobil Chemical Key statement: The present invention includes compositions suitable for air barriers such as innerliners where adhesion to tire carcass carcass, carcase 1. the body of an animal killed for meat. The head, the legs below the knees and hocks, the tail, the skin and most of the viscera are removed. The kidneys are left in and in most instances the body is split down the middle through the sternum and the vertebral materials (e.g., SBR SBR - Spectral Band Replication ) 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 halogenated pertaining to a substance to which a halogen is added. halogenated salicylanilides see rafoxanide, clioxanide. terpolymer ter·pol·y·mer n. A polymer that consists of three distinct monomers. [Latin ter, thrice; see trei- in Indo-European roots + polymer.] of [C.sub.4] to [C.sub.8 ]isoolefin derived units, [C.sub.4] to [C.sub.14] 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 diluent /dil·u·ent/ (dil´oo-int) 1. causing dilution. 2. an agent that dilutes or renders less potent or irritant. dil·u·ent adj. Serving to dilute. n. [C.sub.4] to [C.sub.8] isoolefin monomers [C.sub.4] to [C.sub.14] mul-tiolefin monomers and p-alkylstyrene monomers in the presence of a Lewis acid and at least one initiator to produce the terpolymer. |
