Synthesis and characterization of terminally functionalized and epoxidized hydroxyl-terminated polybutadiene

Pyridyl N-oxide derivatives of hydroxyl terminated polybutadiene-pyridine (HTPB-PY) were synthesized via functionalization on terminal carbon atoms of HTPB backbone by 2-chloropyridine and epoxidation of C=C bonds and N atoms using in situ generated dimethyl dioxirane (DMD). 1HNMR, 13CNMR, 14NNMR, and FT–IR spectroscopy techniques used in order to investigate the structural elucidation of products. In this synthesis method, HTPB terminal hydroxyl groups have preserved unchanged without applying any conditional controllers.
