  • Publication number: 20090018297
    Abstract: A halogenated butyl polymer having improved properties, the butyl polymer derived from a monomer mixture comprising a C4 to C8 monoolefin monomer, a C4 to C14 multiolefin monomer and a styrenic monomer with a catalyst system to produce the butyl polymer. The improved properties include faster cure, higher maximum torque, higher delta torque, relatively stable modulus over time, improved hot air aging properties and improved aged flexure properties. These improved properties are believed to result from direct interaction between the styrenic moieties in the polymer backbone with a crosslinking agent added to vulcanize the halogenated butyl rubber.

    Abstract: A co-polymer of isobutene and 4-bromo-3-methyl-1-butene formed by direct co-polymerization in a single-step process. A continuous process for forming the co-polymer preferably comprises periodic or semi-continuous addition of catalyst to a mixed monomer solution. Semi-continuous reverse addition of the mixed monomer solution to a pre-provided catalyst solution may also be employed. The co-polymer exhibits allylic bromide functionality and is advantageously curable by either ZnO curing systems or sulfur-based curing systems.

  • Patent number: 7087654
    Abstract: The invention provides ion exchange and electrochemical methods and devices employing anion exchange polymers produced by substantially simultaneous quaternization and polymerization reactions. Anion selective polymers are produced in accordance with the invention by combining, an ethylenic tertiary amine monomer, an alkylating agent having a boiling point temperature of at least about 100° C., and a cross-linking agent in the presence of a polymerizing agent for a time and at a temperature sufficient to form the polymer. The alkylating agent and the cross-linking agent may be the same compound, a cross-linking alkylating agent. The polymers may be produced in the presence of solvents and/or in the presence of diluting monomers which are incorporated into the polymers.
