Laser pyrolysis of hydroxyl-terminated polybutadiene
Journal of Propulsion and Power, 1996A method was developed for measuring the dynamic regression rate and plume transmission loss during laser pyrolysis of polymeric binder materials. This method was applied to an investigation of the thermal decomposition of hydroxyl-terminated polybutadiene.

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 ...

Azo initiators for the preparation of hydroxyl‐terminated polybutadienes
Journal of Polymer Science: Polymer Chemistry Edition, 1983AbstractAzo compounds such as di(4‐hydroxybutyl)‐2,2′‐azobisisobutyrate, di(3‐hydroxybutyl)‐2,2′‐azobisisobutyrate, di(2‐hydroxypropyl)‐2,2′‐azobisisobutyrate, and di(2‐hydroxyethyl)‐2,2′‐azobisisobutyrate were prepared and used as initiators for the preparation of hydroxyl‐terminated polybutadienes (HTPBs) of molecular weight (M̄n) ranging from 2000 ...

Functionality Distribution of Carboxyl- and Hydroxyl-Terminated Polybutadiene
Journal of Macromolecular Science: Part A - Chemistry, 1973Abstract Elurion from silica gel was used to fractionate liquid polymers according to the number of chemically reactive groups per molecule (the functionality). Methods are presented for the functionality fractionation of high and low functionality carboxyl-terminated polybutadiene (CTPB).

Properties of hydroxyl‐terminated polybutadiene‐urethane systems
Journal of Applied Polymer Science, 1971AbstractThe properties of liquid hydroxyl‐terminated polybutadiene (HTPB) stocks crosslinked with isocyanates of different functionalities were intensively investigated. The stocks were modified by inclusion of small proportions of various low molecular weight diols to increase the urethane concentration. The following studies were carried out: (1) the

Combinations of hydroxyl‐terminated polybutadiene and boron
Journal of Polymer Science: Polymer Chemistry Edition, 1985AbstractMixing and curing experiments with suspensions of boron in hydroxyl‐terminated polybutadiene (HTPB) have been performed. In kneading experiments on a plastograph very high viscous masses with bad curing properties were obtained. The experiments indicated that HTPB is attached with its OH groups to acidic impurities on the surface of the boron ...

Terminal functionalized hydroxyl‐terminated polybutadiene: An energetic binder for propellant
Journal of Applied Polymer Science, 2009AbstractWe report the functionalization of hydroxyl terminated polybutadiene (HTPB) backbone by covalently attaching 1‐chloro‐2, 4‐dinitrobenzene (DNCB) at the terminal carbon atoms of the HTPB. The modification of the HTPB by the DNCB does not alter the unique physico–chemical properties and the microstructure of the parent HTPB.

Polymer Bulletin, 2011
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).

Studies on Hydroxyl Terminated Polybutadiene Toughened Phenolic Resin
High Performance Polymers, 2006Phenolic novolac was modified with hydroxyl terminated polybutadiene (HTPB) using resole as compatibilizer. These systems were characterized by differential scanning calorimetry, and IR analysis. Neat resin castings were prepared with varying percentages of HTPB.

Polyurethane based on hydroxyl‐terminated polybutadienes
British Polymer Journal, 1971AbstractButadiene has been found to homopolymerise and copolymerise with other reactive vinyl monomers to yield unique liquid polymers which are terminated with reactive allylic hydroxyl groups. Through the use of an isocyanate cure reaction they offer a route to liquid castable general purpose elastomers, capable of reinforcement with various fillers ...
