  • Patent number: 8575257
    Abstract: A flame retardant brominated rubber polymeric composition, wherein the composition can include ethylene propylene ethylidene norbornene rubber polymer and from 12 weight percent to 55 weight percent of bromine covalently bonded thereto. The method can include dissolving a liquid ethylene propylene ethylidene norbornene rubber polymer in hexane with myrcene, forming the composition. The method can include dissolving ethylene propylene ethylidene norbornene rubber polymer in hexane, forming a solution, and adding bromine, or blending N-bromo-succinimide into the solution, forming a suspension. The method can include heating the suspension and stifling the suspension until all bromine in the N-bromo-succinimide has reacted with the ethylene propylene ethylidene norbornene rubber polymer, forming the composition as a solid in a liquid. The method can include removing the liquid from the solid, and flashing off the hexane from the liquid to extract the composition.

  • Patent number: 8329794
    Abstract: A polymer composition of a compatibilized silica in blends of acrylonitrile butadiene polymer and styrene butadiene polymer comprising six to ninety percent by weight of a compatibilized silica, at least one percent by weight of a coupling agent, at least one percent by weight of a styrene butadiene polymer, and at least one percent by weight of an acrylonitrile butadiene polymer is described herein. The polymer composition can have a minimum amount of at least ten percent by weight of 15:50 ratio, acrylonitrile to butadiene polymer, with the remainder being compatibilized silica.

  • Publication number: 20110166264
    Abstract: An elastomeric thermoplastic non-vulcanized terpolymer composition formed from acrylonitrile, styrene, and liquid 1,3-butadiene is disclosed herein. The terpolymer can have from 20 percent by weight to 50 percent by weight of the acrylonitrile, from 0.5 percent by weight to 20 percent by weight of the styrene, and from 30 percent by weight to 79.5 percent by weight of the butadiene. The acrylonitrile can be cross-linked to the styrene. The thermoplastic non-vulcanized terpolymer can include fillers, UV stabilizers, and plasticizers. Also disclosed is an article formed by the elastomeric thermoplastic non-vulcanized terpolymer and a process for making the composition.

  • Publication number: 20110166265
    Abstract: High structure carbon black-styrene butadiene compositions and methods for making such are provided herein. In addition, articles made from the high structure carbon black-styrene butadiene compositions are also provided. The method can include high shear grinding a carbon black comprising from 1 percent by weight to 50 percent by weight of high structure carbon black that forms shear ground carbon black, and combining the shear grinded carbon black with water to form a carbon black slurry.

  • Publication number: 20110166262
    Abstract: A process for forming a compatibilized silica and nitrile polymer blend in latex form is described herein. The process can include treating a silica with a coupling agent in aqueous suspension to form a compatibilized silica slurry. The coupling agent can have the capacity of chemically reacting with the surface of the silica to bond the coupling agent thereto. The process can include blending at least a portion of the compatibilized silica slurry into a styrene butadiene polymer latex, forming a silica styrene butadiene polymer latex, and blending at least a portion of the compatibilized silica slurry into an acrylonitrile butadiene polymer latex, forming a silica acrylonitrile butadiene polymer latex. The process can include blending the silica styrene butadiene polymer latex with the silica acrylonitrile butadiene polymer latex, forming the compatibilized silica and nitrile polymer blend.

  • Patent number: 6506842
    Abstract: Rheology-modified thermoplastic elastomer compositions are prepared by peroxide modification of a melt blend of an ethylene/&agr;-olefin polymer or a diene-modified ethylene/&agr;-olefin polymer and a high melting polymer such as polypropylene or a propylene/&agr;-olefin copolymer. The resulting compositions have an elastomeric phase, a non-elastomeric phase and certain physical properties that exceed those of a like composition that is not rheology-modified. The compositions can be used to make a variety of articles of manufacture via conventional procedures.
