    Abstract: A blended multimodal polymer product is disclosed that comprises a first polymer, wherein the first polymer is a homopolymer of propylene or a propylene copolymer having an ethylene or a C4 to C10 olefin comonomer; and a second polymer, wherein the second polymer is a propylene homopolymer and a propylene copolymer having an ethylene or a C4 to C10 olefin comonomer, and wherein the first polymer and second polymer have a difference in heat of fusion of about 25 J/g or more. Methods for making such a polymer product using at least two reactors in parallel and for separating a propylene-based polymer from a solvent using a liquid-phase separator are also disclosed.

    Abstract: High Mooney viscosity elastomers having low volatiles content, and processes for producing such elastomers, are provided herein. In particular aspects, the elastomers are metallocene-catalyzed elastomers, such as mEPDM elastomers. Processes for producing such elastomers include devolatilization of an elastomer stream comprising such elastomers, using a kneader. The kneader is counterintuitively operated such that the internal agitating paddles rotate at relatively low speeds. It is believed these low speeds help maintain the elastomer stream as a toffee-like composition, preventing the elastomer stream within the kneader from becoming a crumbly composition, which is difficult to devolatilize.

    Abstract: The present invention relates to a process of forming a polymer, the process comprising polymerizing olefin monomers to form a reaction mixture, treating the reaction mixture to form a first polymer-rich phase, treating the first polymer-rich phase to form a second polymer-rich phase, and devolatilizing the second polymer-rich phase, the process further comprising at least one step of adjusting the temperature of a first and/or the second polymer-rich phase before the devolatilization. The present invention also relates to a plant that is useful for the process provided above.
