AbstractCrosslinkable 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 Mn1 /Mn2 >7, Mn2 >3000 and 0.7ࣙ(A1 /(A1 +A2))ࣙ0.15 wherein Mn1 represents the number average molecular weight of the first deconvoluted component, Mn2 represents the number average molecular weight of the second deconvoluted component, and A1 and A2 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.
