摘要： Disclosed herein are methods of controlling polymer properties in polymerization processes that use a chromium-based catalyst. An embodiment discloses a method of producing a polyolefin comprising: contacting a reaction mixture and a reduced chromium oxide catalyst in a gas-phase reactor to produce the polyolefin, wherein the reaction mixture comprises a monomer and a co-monomer; and changing a reaction temperature in the gas- phase reactor by about 1° C or more whereby a gas molar ratio of the co-monomer to the monomer is changed by about 2% or more and a co-monomer content of the polyolefin at substantially constant density is changed by about 2% or more. Additional methods and compositions are also provided.

摘要： The invention relates to a bimodal polymerization catalyst system comprising:
a non-metallocene olefin polymerization catalyst; and
a zirconocene catalyst of Formula I:
where R 4 is independently a C 1 to C 20 alkyl, aryl or aralkyl group or a hydrogen, where R 3 is a C 1 to C 20 alkyl, aryl or aralkyl group, and where each X is independently a halide, C 1 to C 20 alkyl, aralkyl group or hydrogen, and where:
R 1 is a C 1 alkyl and R 2 is a C 3 alkyl.-

摘要： A method of producing a polyolefin comprising:
contacting a reaction mixture and a reduced chromium oxide catalyst in a gas-phase reactor to produce the polyolefin, wherein the reaction mixture comprises ethylene and a comonomer, and wherein the polyolefin is characterized by (i) a modified-Charpy impact strength of about 20 kJ/m 2 or more and (ii) an equivalent stress cracking resistance of about 50 hours or more determined by notched constant ligament stress.-
