Abstract
Liquiflex-H is commercially available hydroxyl terminated polybutadien e (HTPB) produced by Petroflex. It was analyzed by H-1 and C-13 NMR sp ectroscopy 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 discuss ion. HETCOR and COSY pulse sequence NMR techniques were used in this w ork to solve this question.
