摘要： A process for the production of an ethylene alpha-olefin copolymer is disclosed. The process includes polymerizing ethylene and at least one alpha-olefin by contacting the ethylene and the at least one alpha-olefin with a metallocene catalyst in at least one gas phase reactor at a reactor pressure of from 0.7 to 70 bar and a reactor temperature of from 200C to 1500C to form an ethylene alpha-olefin copolymer. The resulting ethylene alpha-olefin copolymer may have a density of 0.927 g/cc or greater and environmental stress crack resistance (ESCR) of 500 hr or more when measured according to ASTM 1693/B in 10% Igepal.

摘要： Low viscosity ethylene acrylic copolymers and blends thereof with other fiber-forming polymers for spunbond and melt blown nonwoven applications. Ethylene/alkyl (meth) acrylate, especially ethylene/methyl acrylate copolymers are found to be suitable for fiber-forming operations, especially melt blowing when the melt index is at least about 10. Blends of the copolymer with other fiber-forming polymers are especially suitable for fiber-forming operations. The nonwoven products of the copolymers and blends of the invention show a good degree of elongation making them especially suitable for certain fabric applications and new uses. The nonwoven fabrics are comprised of fibers of the copolymers and blends, having a diameter of about 1-40 microns, Larger fibers may also be formed by various techniques.
