<p><P>PROBLEM TO BE SOLVED: To provide a conjugated diene polymer giving a polymer composition excellent in fuel consumption economy, the polymer composition obtained by mixing the polymer and a filler, and a method for producing the conjugated diene polymer. <P>SOLUTION: The conjugated diene polymer comprises a conjugated diene unit and a vinylsilane unit, wherein a silicon atom of vinylsilane has a hydroxy group, a (substituted) hydrocarbyl group, or a secondary amino group having a 1-6C (substituted) hydrocarbyl group (the hydrocarbyl group may form a nitrogen atom-containing ring). At least one terminus of the conjugated diene polymer is modified with a compound having a group represented by formula (II) wherein a functional group having a nitrogen atom is bonded to a carbonyl group via a 1-20C (substituted) hydrocarbylene group or directly (where, p is 0 or 1, T is the 1-20C (substituted)hydrocarbylene group, and A is the functional group having a nitrogen atom). <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
