    摘要: A process for fluid phase in-line blending of plasticized polymers is provided. The process includes providing two or more reactor trains configured in parallel and a separator for product blending and product-feed separation, wherein one or more of the reactor trains produces one or more polymers and one or more of the reactor trains produces one or more plasticizers; contacting in at least one of the parallel reactor trains olefin monomers, catalyst systems, optional comonomers, optional scavengers, and optional 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 fluid phase polymer-monomer mixture and plasticizer-monomer mixture in each parallel reactor train; passing the reactor effluents through the separator; maintaining the temperature and pressure within the separator above the solid-fluid phase transition point but below the cloud point pressure and temperature to form a fluid-fluid two-phase system including a plasticized polymer-rich blend phase and a monomer-rich phase; and separating the monomer-rich phase from the plasticized polymer-rich blend phase. The polymer-rich blend phase is conveyed to a downstream finishing stage for further monomer stripping, drying and/or pelletizing to form a plasticized polymer product blend. Suitable plasticizers for in-line production and blending include polyalphaolefin oligomers, polybutenes, low glass transition temperature polymers and combinations thereof.

    摘要: This invention relates to olefin polymers particularly suited to satisfying the dielectric properties required in electrical device use. The olefin polymers can be prepared by contacting polymerizable olefin monomers with catalyst complexes of Group 3–11 metal cations and noncoordinating or weakly coordinating anion compounds bound directly to the surfaces of finely divided substrate particles or to polymer chains capable of effective suspension or solvation in polymerization solvents or diluents under solution polymerization conditions. Thus, the invention includes polyolefin products prepared by the invention processes, particularly ethylene-containing copolymers, having insignificant levels of mobile, negatively charged particles as detectable by Time of Flight SIMS.
