    摘要: The invention relates to a process for the polymerization of olefins comprising the comprising the steps of a. Polymerizing olefins in a reaction mixture comprising monomers, diluent, processing aids to prepare a product stream comprising polyolefins, monomers and diluent; b. Removing the polyolefins from the product stream to obtain a purge stream; c. Removing gaseous components from the purge stream to obtain a liquid fraction; d. Treating the liquid fraction with at least one ionic liquid to obtain a fraction containing unsaturated hydrocarbons; e. Recycling the fraction containing unsaturated hydrocarbons to the reaction mixture, optionally after purification of said fraction containing unsaturated hydrocarbons. The invention also relates to an olefin polymerization system comprising a polymerization reactor, a purge vessel, a vent gas recovery and an ionic liquid separator for separating liquid alkenes from liquid alkanes, wherein the liquid alkenes which are separated from the alkanes in the ionic liquid separator can be recycled to the polymerization reactor.

    摘要: Disclosed are a method of preparing a modified conjugated diene-based polymer, a modified conjugated diene-based polymer prepared thereby, a rubber composition including the modified conjugated diene-based polymer, and a tire including the rubber composition. The method of preparing the modified conjugated diene-based polymer includes (a) polymerizing a vinyl aromatic monomer and a conjugated diene monomer through continuous solution polymerization using a multifunctional anionic polymerization initiator in the presence of a hydrocarbon solvent, thus forming an active polymer having a reactive end; and (b) coupling or linking the reactive end of the active polymer with an aminosiloxane compound.
