Method for producing polymeric compositions including functionalized polymers

A method for producing a functionalized polymer, the method comprising the steps of polymerizing conjugated diene monomer, optionally together with a copolymerizable monomer, within a solvent to produce a polymerization mixture including a polymer having a reactive terminus, coupling a portion of the polymer having a reactive terminus with a hydrocarbyloxysiloxane to produce a polymerization mixture including polymer coupled with the hydrocarbyloxysiloxane and residual polymer having a reactive terminues, reacting the residual polymer having a reactive terminus with a functionalizing agent having at least one hydrocarbyloxy functionality to produce a polymerization mixture including a functionalized polymer and the polymer coupled with the hydrocarbyloxysiloxane, and desolventizing the polymerization mixture including the functionalized polymer and the polymer coupled with the hydrocarbyloxysiloxane. 种用于产生官能化聚合物的方法，所述方法包括以下步骤：在溶剂中使共轭二烯单体任选地与可共聚的单体起聚合，以产生包含具有反应性末端的聚合物的聚合混合物；将所述具有反应性末端的聚合物的部分与烃氧基硅氧烷偶联，以产生包含与所述烃
