Publication number: 20090197995Abstract: Provided are elastomeric compositions, such as a tire innerliner, comprising at least one isobutylene based elastomer and at least one hydrocarbon fluid additive (“HFA”). The compositions have improved cold temperature properties and are particularly useful as tire innerliners for an aircraft tire. The use of a HFA in the elastomeric composition may allow for the use of reduced amounts of secondary elastomers, such as natural rubber, while allowing for an improved balance in the composition's brittleness and permeability properties. Examples of useful HFAs include polyalphaolefins, high purity hydrocarbon fluids, and water white group III mineral oils.Type: ApplicationFiled: March 11, 2009Publication date: August 6, 2009Inventors: Donald S. Tracey, Andy H. Tsou, Bryan R. Chapman, Bruce A. Harrington, David B. Dunaway

Publication number: 20090163642Abstract: An in-line fluid phase process for blending low crystallinity polymer components (LCPCs) and high crystallinity polymer components (HCPCs) to form pellet-stable polyolefin pellets is provided. The in-line process for producing the blend includes providing two or more parallel reactor trains and one or more separators for product blending and product-feed separation; wherein the two or more reactor trains producting the LCPC and HCPC blend components operate under fluid phase bulk homogeneous conditions, and at least one of the reactor trains operates under supercritical conditions. The HCPC blend component is a high crystallinity polypropylene-based polymer. The LCPC blend component is a low crystallinity ethylene-based or propylene-based polymer. The resultant blend pellets exhibit a reduced tendency or an eliminated tendency to agglomerate during shipping, handling and storage.Type: ApplicationFiled: December 18, 2008Publication date: June 25, 2009Inventors: Gabor Kiss, Alan Anthony Galuska
