    Abstract: A process for in-line blending of plasticizers and polymers in a single reactor train including one or more serially configured reactors, a high-pressure separator downstream fluidly connected to the train, and one or more storage tanks, wherein the train produces one or more base polymer components and the one or more storage tanks store one or more off-line produced plasticizers; contacting in the reactor train olefin monomers, catalyst systems and optional comonomers, scavengers, diluents or solvents, at a temperature above the solid-fluid phase transition temperature of the polymerization system and a pressure no lower than 10 MPa below the cloud point pressure of the polymerization system and less than 1500 MPa, forming a reactor effluent including a homogeneous mixture; passing the reactor effluent through theseparator to separate a monomer-rich phase from a polymer-rich phase; and feeding the plasticizers to the process after the reactor train.

    Abstract: An in-line fluid phase process for blending low crystallinity polymer components (LCPCs) and high crystallinity polymer components (HCPCs) to form pellet-stable polyolefin pellets is provided. The in-line process for producing the blend includes providing two or more parallel reactor trains and one or more separators for product blending and product-feed separation; wherein the two or more reactor trains producting the LCPC and HCPC blend components operate under fluid phase bulk homogeneous conditions, and at least one of the reactor trains operates under supercritical conditions. The HCPC blend component is a high crystallinity polypropylene-based polymer. The LCPC blend component is a low crystallinity ethylene-based or propylene-based polymer. The resultant blend pellets exhibit a reduced tendency or an eliminated tendency to agglomerate during shipping, handling and storage.

    Abstract: A monomer recycle process for fluid phase in-line blending of polymers is provided. The monomer recycle process includes providing a first group (G1) of one or more reactor trains and a second group (G2) of one or more reactor trains and one or more separators fluidly connected to G1 and G2; polymerizing in each of G1 and G2 olefin monomers to form homogenous fluid phase polymer-monomer mixtures wherein each of the G1 and G2 have at least one common monomer; passing the reactor effluents from G1 through the G1 separators to separate a monomer-rich phase from a polymer-enriched phase, passing the polymer-enriched phase and the reactor effluents from G2 into the G2 separator to separate another monomer-rich phase from a polymer-rich blend, and recycling to each of G1 and G2 the separated monomer-rich phase from the G1 and G2 separators, respectively.
