Abstract
The invention includes a siloxy-amine functionalized rubbery polymer, which exhibits good reinforcing characteristics and filler dispersing effect, a method for making, and a rubber composition including the same. In one embodiment, a process for manufacturing includes polymerizing a conjugated diene monomer using an organolithium compound as an initiator in a hydrocarbon solvent. Next, an active terminal end of the polymer is reacted with a functionalized terminating agent represented by:RN—(CH)Si(OR),  Formula (I)wherein R, in combination with the nitrogen (N) atom, is a substituted or unsubstituted heterocyclic aromatic or non-aromatic compound which includes a ring structure with one or more nitrogen atoms as part of the ring; Rrepresents a group having 1 to 18 carbon atoms selected from an alkyl, a cycloalkyl, an allyl, or an aryl; and X is an integer from 1 to 20.
