摘要： A method of processing polyethylene for use as an extruded blow molding resin to improve the properties and processability thereof is accomplished by modifying a polyethylene resin having a molecular weight distribution (Mw/Mn) of less than about 10. The modification is carried out by the addition of a free radical initiator to the resin during extrusion of the resin to increase the rheological breadth of the polyethylene from about 10% to about 60% compared to unmodified polyethylene resin extruded under similar conditions. In another aspect of the invention, a polyethylene resin having higher melt index is processed to provide a desired final melt index by the addition of a free radical initiator where it would otherwise be necessary to utilize a resin having lower melt flow, and which is more difficult to process. Improvements in color can also be obtained.

摘要： Process for the polymerization of ethylene to produce a polymer of enhanced long chain branching. Ethylene and hydrogen are introduced into a first reaction zone to produce an ethylene polymer having a first molecular weight distribution. The polymer from the first reaction zone is applied to a second reaction zone along with ethylene and a C3-C8 alpha-olefin monomer. The second reaction zone is operated to produce a copolymer having a second molecular weight distribution different from the first molecular weight distribution. A polymer fluff of bimodal molecular weight distribution is recovered from the second reaction zone and heated to melt the fluff and then extruded. Concomitantly with the heating and or extrusion, the polymer fluff is treated in order to enhance the long chain branching and reduce the melt index MI5 of the polymer product.
