The projectile's rocket motor ... contains about 0.5 kg of aluminised rubbery HTPB (hydroxy-terminated polybutadiene) propellant set in an intricate shape to give the maximum possible burning area.


The liquid hydroxy-terminated polybutadiene Krasol LBH 3000 was used as a polyol for the preparation of polyurethane elastomers. ... Size exclusion chromatography and liquid adsorption chromatography were used to characterise low-molecular weight hydroxy-terminated polybutadienes prepared by anionic polymerisation.


hydroxy terminated polybutadiene (1, 2 addition), ... hydroxy terminated polybutadiene (1, 4 addition) ...


hydroxy-: [A] chemical prefix indicating the OH group in an organic compound, such as hydroxybenzene for phenol, C6H5OH ... [oxy- and hydroxyl- are to be avoided in this sense.]


HTPB: This might be an in-house or a non-recognized abbreviation; not to be used alone, to avoid any risk of confusion.
