摘要： A rigid polyurethane (PU) foam having a number average cell size of no greater than 10μm. The rigid PU foam is prepared by a method that includes using carbon dioxide to provide a pressure at a first predetermined value on a polyol mixture. The polyol mixture includes a polyol, a catalyst and a surfactant. The pressure is maintained at the first predetermined value for a first predetermined time to increase a carbon dioxide concentration in the polyol mixture. An isocyanate is mixed with the polyol mixture to form a polyurethane reaction mixture. The pressure on the polyurethane reaction mixture is optionally maintained at the first predetermined value for a second predetermined time. The pressure on the polyurethane reaction mixture is then increased from the first predetermined value to a second predetermined value greater than the first predetermined value. The polyurethane reaction mixture is then released at a predetermined depressurization rate from the pressure after a third predetermined time to prepare the rigid PU foam, where the third predetermined time is less than 30 minutes.

摘要： A polymer composition comprises a low-molecular-weight (LMW) ethylene polymer component and a high-molecular-weight (HMW) ethylene polymer component coupled with a polysulfonyl azide. Preferably, the LMW polyethylene component and the HMW polyethylene component co-crystallize in the composition such that it exhibits a single or substantially single peak in a lamella thickness distribution (LTD) curve. The ethylene polymer for the LMW and the HMW polyethylene components can be either homopolymer or ethylene copolymer. Preferably, both components are an ethylene copolymer of the same, or different, composition (that is, with the same or different comonomers). A method of making a pipe that includes selecting a polymer composition having a substantially single peak in the LTD curve is described. Compositions comprising a chromium-catalyzed ethylene polymer, coupled with a polysulfonyl azide are also described herein.

摘要： The present invention relates to crosslinked, olefin elastic fibers where the olefin materials are specifically selected to provide a more robust fiber with higher tenacity and greater temperature stability. Such fibers will be less subject to breakage during fiber spinning and post-spinning (downstream processing) operations including spool formation and unwinding. The specific olefin material used is a blend having an overall melt index (I2) of less than 2.5 g/10 min before crosslinking with a density in the range of 0.865 to 0.885 g/cm 3 . One component of the blend will be characterized as having either a density in the range of from 0.855 to 0.88 g/cm 3 or a residual crystallinity at 80 °C of greater than 9 percent but not both. The at least one other component will meet at least whichever characteristic the first component does not meet.

摘要： The present invention is a rheology-modifiable polymeric composition or a free-radical crosslinkable polymeric composition, wherein the resulting rheologymodifying bond or crosslinking bond is a thermally-reversible bond. The resulting polymer is prepared from at least one polymer which upon forming free radicals preferentially degrades or carbon-carbon crosslinks. The present invention permits suppression of the preferential reaction while permitting the polymer to be coupled or crosslinked through a thermally-reversible bond. Suppressing the undesirable degradation or carbon-carbon crosslinking reaction and permitting the desirable reaction yield a rheology-modified polymer or a free-radical thermally-reversibly crosslinked polymer.
