    摘要： This disclosure relates to ethylene interpolymer products comprising a Melt Flow-Intrinsic Viscosity Index value, MFIVI, of from ≥ 0.05 to ≤ 0.80; a first derivative of a melt flow distribution function, formula (I) at a loading of 4000 g, of from ≥ -1.85 to ≤ -1.51; a sum of unsaturation, SUMU, from ≥ 0.047 to ≤ 0.100 unsaturations per 100 carbon atoms; and a residual catalytic metal of from ≥ 0.03 to ≤ 5 ppm of hafnium. Ethylene interpolymer products comprise at least two ethylene interpolymers. Ethylene interpolymer products are characterized by a melt index (I2) from 0.3 to 500 dg/minute, a density from 0.855 to 0.975 g/cc and from 0 to 25 mole percent of one or more a-olefins. Ethylene interpolymer products have polydispersity, Mw/Mn, from 1.7 to 25; and CDBI50 values from 1% to 98%. These ethylene interpolymer products have utility in flexible as well as rigid applications.

    摘要： A solution polymerization process that consumes less energy comprising: injecting feeds into one or more reactors to form a polyethylene in a single liquid phase, or optionally two liquid phases; deactivating the single or dual liquid phase; a first V/L separator separates the deactivated phase into a first bottom stream and a first overhead stream; the first overhead stream passes to a distillation column and the first bottom stream enters a second V/L separator, forming a second overhead stream and a second bottom stream; the second bottom stream enters a third V/L separator, forming a third overhead stream and a third bottom stream; the third bottom stream passes to polymer recovery; the second and third overhead stream are combined, condensed and purified, forming a purified solvent that is recycled to said reactors.

    摘要： This disclosure relates to ethylene interpolymer product having intermediate branching. Intermediate branching was defined as branching that was longer than the branch length due to comonomer and shorter than the entanglement molecular weight (M e ). Intermediately branched ethylene interpolymer products were produced in a continuous solution polymerization process employing an intermediate branching catalyst formulation. Intermediately branched ethylene interpolymer products were characterized by a Non-Comonomer Index Distribution (NCID i ), a melt index from 0.3 to 500 dg/minute, a density from 0.858 to 0.965 g/cm 3 , a polydispersity (M w /M n ) from about 2 to about 25 and a CDBI 50 from about 10% to about 98%. A method based on triple detection cross fractionation chromatography (3D-CFC) was disclosed to measure NCID i .
