    摘要: A method of lowering MFR response of a high-melt-flow-rate-polymer-producing metallocene catalyst is provided. The method includes contacting the metallocene catalyst with a sufficient quantity of α,ω-diene monomer such that when the catalyst composition is contacted with polymerizable reactants under suitable polymerization conditions, the resulting polymer has an MFR rate in the range of 0.1 to 1000. Hydrogen and ethylene may also be present in the polymerization. Additionally a catalyst composition is provided which includes a high-melt-flow-rate-polymer-producing metallocene catalyst and a sufficient quantity of α,ω-diene monomers such that when the catalyst composition is contacted with a monomer under polymerization conditions, the resulting polymer has an MFR rate in the range of 0.1 to 1000.

    摘要: This invention relates to a method to process narrow molecular weight distribution polyolefins, particularly thermoplastics, polyethylenes, polypropylenes, and polyacrylates, whether they are homopolymers or copolymers. The process may be used in any extruder and is typically implemented along the extruder screw and/or barrel by heating the first zone the screw/barrel to place the polyolefin into a molten, flowable state. Thereafter, the polymer is cooled in the second heating zone to a point 50.degree. C. above or 10.degree. C. below the crystalline melting temperature of the polymer and thereafter is reheated in the final heating zone to a molten, flowable state and finally extruding it within 5 seconds or less through the die.
