Liquiflex-H is commercially available hydroxyl terminated polybutadiene (HTPB) produced by Petroflex. It was analyzed by 1H and 13C NMR spectroscopy with regard to three main hydroxylated end groups. The NMR assignments related to three main alcoholic functions has raised some controversy in the literature and is considered further in our discussion. HETCOR and COSY pulse sequence NMR techniques were used in this work to solve this question.
