摘要： A continuous process for producing conjugated diene polymers comprising the steps of contacting, within an hydrocarbon solvent and within a continuous reactor, conjugated diene monomer and a catalyst composition prepared by combining: (a) a lanthanide compound, (b) an alkylating agent, and (c) a halogen-containing compound, and maintaining a non-ideal flow pattern within the continuous reactor so that 10% of the reagents entering the reactor at a reference time t0 are still present within the continuous reactor at a time t0 + xtrt, where trt is the residence time corresponding to ideal flow within the continuous reactor and x is a numeral greater than 1.5.

摘要： A method for preparing a functionalized polymer comprising the steps of preparing a pseudo-living polymer by polymerizing conjugated diene monomer with a lanthanide-based catalyts, and reacting the pseudo-living polymer with at least one functionalizing agent defined by the formula (I) or (II) where Z is a substituent that will react or interact with organic or inorganic fillers; R1 is a single bond or a divalent organic group; R2 is a monovalent organic group or a divalent organic group that forms a cyclic organic group with R?3 or R4; R3¿ is a single bond, a divalent organic group, or a trivalent organic group that forms a cyclic organic group with R?2, R4, or R5; R4¿ is a monovalent organic group or a divalent organic group that forms a cyclic organic group with R?2, R3, or R5; R5¿ is a monovalent organic group or a divalent organic group that forms a cyclic organic group with R?2, R3, or R4; and R1, R2R3, R4, R5¿ and Z are substituents that will not protonate pseudo-living polymer. Also vulcanizable compositions containing functionalized polymers having filler-interactive substituents that are useful in the production of tires and other industrial products.
