PROCESS TO MAKE HIGH DENSITY ETHYLENE-BASED POLYMER COMPOSITIONS WITH HIGH MELT STRENGTH
A process for producing a composition comprising A) an ethylene-based polymer that has a density greater than, or equal to, 0.940 g/cc, and B) an ethylene homopolymer formed by polymerizing a reaction mixture comprising ethylene, using a free-radical, high pressure polymerization process includes ad...

| description | A process for producing a composition comprising A) an ethylene-based polymer that has a density greater than, or equal to, 0.940 g/cc, and B) an ethylene homopolymer formed by polymerizing a reaction mixture comprising ethylene, using a free-radical, high pressure polymerization process includes adding component (A) to a molten stream of component (B) after component (B) exits the separator and before component (B) is solidified in the pelletizer. A polymerization configuration for producing the composition includes at least one reactor, at least one separator, at least one pelletizer, and a device used to feed component (A), in the molten state, to a molten stream of component (B) before the pelletizer. The composition has a ratio of the melt strength of the composition to the melt strength of component (B) is greater than or equal to 1.04 and a density of greater than 0.920 g/cc. |
