Polymer based on conjugated diene, polymer composition based on conjugated diene and method for producing polymer based on conjugated diene

摘要

A polymer based on a conjugated diene comprising a monomer unit based on a conjugated diene, a monomer unit based on a compound represented by the following formula (1), and a monomer unit based on a compound represented by the following formula (2).wherein R11 means a hydrogen atom or hydrocarbon residue, m is an integer of 0 or 1, R12 means a hydrocarbon residue, and X1, X2 and X3 each independently mean a substituted aminorest or a hydrocarbon residue, optionally having a substituent, provided that at least one of X1, X2 and X3 is a substituted aminorest.wherein R21 means a hydrogen atom or hydrocarbon residue, n is an integer of 0 or 1R22 means a hydrocarbon residue, and A means a substituted amino ester or a nitrogen-containing heterocyclic residue.
