摘要： In a process for producing a heterogeneous polymer blend, at least one first monomer is polymerized in a first reaction zone in the presence of a supported catalyst to produce a thermoplastic first polymer having a crystallinity of at least 30%. At least part of said first polymer is then contacted with at least one second monomer and at least one polyene in a second reaction zone under conditions sufficient to polymerize said second monomer to produce a second polymer having a crystallinity of less than 20%. The second polymer is at least partially cross-linked in the second reaction zone such that at least a fraction of the second polymer is insoluble in xylene and such that the first and second polymers form different phases of the blend.

摘要： A process is provided for extruding a bimodal polyethylene resin. The process includes providing a polyethylene homopolymer or copolymer resin having a bimodal molecular weight distribution; conveying the resin through an extruder having a feed zone in which the resin is not melted, a melt-mixing zone in which at least a portion of the resin is melted, and a melt zone in which the resin is in a molten state, each zone being partially filled with the resin; and contacting the molten resin in the melt zone with a gas mixture of 8 to 40% by volume O2.

摘要： This invention is directed to processes of making polymer in the presence of a hydrofluorocarbon or perfluorocarbon and recovering the polymer. The processes provided enable polymerization processes to be practiced with minimal fouling in the reaction system, and to the recovery of the hydrofluorocarbon and other hydrocarbons such as hydrocarbons for reuse in the process or hydrocarbon by-products from the polymerization process. The invention is particularly beneficial in the production of ethylene based polymers using bulky ligand metallocene-type catalyst systems.
