NMR Analysis of Thermally‐Oxidized Hydroxyl‐Terminated Polybutadiene (HTPB)
ChemistrySelectNuclear magnetic resonance spectroscopy was employed to monitor the change in chemical structures, olefin units (cis, trans and vinyl) and hydroxyl value on stabilized Hydroxyl‐terminated polybutadiene (HTPB) under accelerated ageing condition.

Characterization of hydroxyl-terminated polybutadiene
Polymer Bulletin, 1997The structures of hydroxyl terminated polybutadienes (HTPB) obtained by free radical polymerization of butadiene in ethanol medium initiated by thermal and photochemical hydrogen peroxide decomposition were studied. The incorporation of alcohol in the polymer chain ends was evidenced by 1 H and 13 C NMR spectroscopy.

Functional Alkyl‐Ferrocene Grafted Hydroxyl Terminated Polybutadiene
ChemistrySelect, 2021Abstract Grafting of functional ferrocene molecules in the backbone of hydroxyl terminated polybutadiene (HTPB) without altering physical characteristics such as viscosity, hydroxyl value, molecular weight of the pristine HTPB remains as an important challenge owing to the difficulty in synthesizing appropriate functional ferrocene ...

Characterization of hydroxyl-terminated polybutadiene
Polymer Bulletin, 1994Liquiflex is a commercial hydroxyl terminated polybutadiene (HTPB) produced by Brazilian technology. It was characterized with respect to molecular weight, functionallty, microstructure and hydroxyl group types. The results were compared with those obtained for R45M and R45TH Atochem products.

Characterization of hydroxyl-terminated polybutadiene
Polymer Bulletin, 1995A comparison between the molecular structure of conventional and low molecular weight hydroxyl terminated polybutadienes (HTPBs) is presented. The conventional HTPB samples were R45M, R45HT (Atochem), Liquiflex P and H (Petroflex, Brazil), and the low molecular weight ones were R20LM (Atochem) and two laboratory synthesized materials.

Molecular characterization of hydroxyl‐terminated polybutadienes
Journal of Applied Polymer Science, 1984AbstractA comparative study has been made on the functionality distribution of two hydroxyl terminated polybutadiene products which are used largely as prepolymers for sealants, adhesives, and solid propellants. They are known to possess nearly the same molecular characteristics.

Dynamic shearing resistance of hydroxyl-terminated polybutadiene (HTPB)
Journal of Applied Physics, 2021Hydroxyl-terminated polybutadiene (HTPB) is a widely used polymeric binder in polymer-bonded explosives (PBXs) and solid rocket propellants. Even though used in small fractions, the elastomeric binder absorbs much of the impact energy and therefore requires careful modeling of its mechanical behavior to accurately simulate the response of PBXs when ...
