    摘要： Crosslinkable polyolefin compositions, articles prepared from such compositions, and processes for making such compositions are described that possess both good processability and fast cure rates. The crosslinkable polyolefin compositions are bidisperse blends of ethylene polymers of the same polymer family having differing number average molecular weights as obtained by deconvolution in which M.sub.n1 /M.sub.n2 >7, M.sub.n2 >3000 and 0.7.gtoreq.(A.sub.1 /(A.sub.1 +A.sub.2)).gtoreq.0.15 wherein M.sub.n1 represents the number average molecular weight of the first deconvoluted component, M.sub.n2 represents the number average molecular weight of the second deconvoluted component, and A.sub.1 and A.sub.2 are the relative proportions of the first and second components. These crosslinkable polyolefin compositions are useful for the manufacture of various articles, such as wire and cable coatings, weather-stripping and seals, gaskets, articles made from foamed and/or sponge-like crosslinked polyolefin or either closed or open cell structure and/or combinations thereof, hollow containers, hollow tanks, medical appliances, drapes and coverings, items of health and personal care, fibers, tapes, tubes, pipes and hoses, bellows, boots, gaiters, footwear, etc.

    摘要： A fuel reforming system, process, and device including a catalytic chamber and a heating chamber. The catalytic chamber, further including a fluid fuel intake and a gaseous fluid exit port and at least one heat exchanger for distributing heat between the heating chamber and the catalytic chamber. The catalytic chamber further including a screen member having a surface, wherein the member includes a catalytic deposit made from a combination of platinum and rhodium alloy. A catalytic conversion of converting liquid fuel to gaseous fuel occurs within the catalytic chamber. Fuel exits the fuel reforming device through a gaseous fluid exit port. In the process of phase change from liquid to gaseous phase, there is no change of chemical composition and C8H18 remains stable throughout, except for an increase in Enthalpy (heat content) per mol.

    摘要： Slush moldable polyolefin powders are prepared by blending a crosslinkable silane-grafted, olefinic interpolymer, optionally containing a crystalline polypropylene homopolymer or interpolymer; and a crosslinked silane-grafted, olefinic interpolymer containing a cure catalyst, the blend optionally containing a crystalline polyolefin powder. The resulting compositions can be slush molded to make a variety of articles of manufacture, especially automotive interior components, having good hot tear properties, low hardness and no glossing after heat aging.
