Process for the production of polymer compositions with excellent processability

Embodiments of the present application are directed to procatalysts, and catalyst systems including procatalysts, including a metal-ligand complex having the structure of formula (Ia):

Spray-dried catalysts containing a germanium-bridged bis-biphenyl-phenoxy organometallic compound for making ethylene-based copolymers

A composition comprising the following components a)-c): a) an alpha composition comprising a multimodal ethylene/alpha-olefin interpolymer, and wherein the alpha composition comprises the following properties: i) an Mz/Mn≥8.0, ii) a density from 0.855 to 0.890 g/cc, iii) a V100 (100° C.)≤2,000 Pa·s, iv) a V1.0 (100° C.)≥15,000 Pa·s, v) a Mn≥16,000 g/mol; b) a peroxide; and c) a silane coupling agent.

Ethylene/alpha-olefin interpolymer based compositions with improved balance of cure and processability

Embodiments of a method for producing a multimodal ethylene-based polymer having a first, second, and third ethylene-based component, wherein the multimodal ethylene based polymer results when ethylene monomer, at least one C-Ccomonomer, solvent, and optionally hydrogen pass through a first solution, and subsequently, a second solution polymerization reactor. The first solution polymerization reactor or the second solution polymerization reactor receives both a first catalyst and a second catalyst, and a third catalyst passes through either the first or second solution polymerization reactors where the first and second catalysts are not already present. Each ethylene-based component is a polymerized reaction product of ethylene monomer and C-Ccomonomer catalyzed by one of the three catalysts.
