摘要： A high density polyethylene (HDPE) film is provided having high biaxial orientation. The film includes HDPE having a density of at least 0.940, and a melt index of from 0.5 to 10. The film is stretched in the machine (longitudinal) direction to a degree of from 5:1 to 8:1, preferably from 6:1 to 7:1. The film is also stretched in the transverse (lateral) direction to a degree of from 6:1 to 15:1, preferably from 9:1 to 13:1. Preferably, the film has an orientation imbalance, with a higher degree of transverse orientation than machine orientation. Skin layers such as heat seal layers can be provided. Preferably, the film contains one or more layers of a casting promoter material employed to promote casting of a high gauge HDPE sheet subsequently high biaxially oriented to provide the film. The film can also be cavitated, or otherwise modified (e.g., corona-treated, coated, metallized, etc.) to provide films suitable for special applications. The film of the invention has superior properties, including lower water vapor transmission rate, better dead-fold, higher tensile strength, and consistent gauge profile. Also provided is a method for making the biaxially oriented film.

摘要： The instant invention relates to a fluid catalytic isoparaffin-olefin alkylation process in which a circulating fluidized-bed reactor is employed and the catalyst is continuously regenerated. A solid catalyst which comprises a large pore zeolite contacts the feed in the riser of the reactor. Both the feed and the catalysts are maintained in vapor phase. Following recovery from the product, at least a portion of the catalyst is recycled to the reactor following steam stripping and gas purging. The remainder is passed to the regenerator for the removal of coke, then is recycled to the riser. C5+ alkylate product and isobutane are separated from the hydrocarbon effluent. Isobutane is recycled to the riser.

摘要： Blown films of linear low density polyethylene are produced by a high stalk process comprising extruding the linear low density polyethylene through an annular die to form an extruded tube of molten material, cooling the extruded tube while drawing the tube so cooled, to maintain the tube diameter identical to that of the annular die and expanding the tube or bubble to attenuate the walls thereof by introducing a gas to the interior of the tube or bubble. The resulting films are characterized by superior impact strength and MD tear resistance.
