Preparation of Hydroxyl-Terminated Polybutadiene with High Cis-1,4 Content

Industrial & Engineering Chemistry Research, 2014
Hydroxyl-terminated polybutadiene (HTPB) with high cis-1,4 content (>95.0%) has been prepared via a two-step method by taking commercial butadiene rubber (BR9000) as a starting material, including the one-pot synthesis of aldehyde-group-terminated polybutadiene (ATPB) in high efficiency and the subsequent reduction reaction.

Tensile property of modified hydroxyl-terminated polybutadiene-based polyurethanes

Journal of Applied Polymer Science, 1997
Modified hydroxyl-terminated polybutadiene (HTPB)-based polyurethanes (PUs) were prepared by three different processes: crosslinkage of the soft segment, complexation of the hard segment, and the interpenetrating network (IPN). Crosslinked PU films were prepared by the addition of a crosslinking agent of divinylbenzene (DVB) to the 4,4 ...

The effect of pressure on the mechanical properties of hydroxyl-terminated polybutadiene-based propellants

Journal of Molecular Modeling
In order to estimate the mechanical behavior of the propellant under working pressures, the effect of pressure on the mechanical properties of hydroxyl-terminated polybutadiene (HTPB) propellants was studied by analyzing the uniaxial tensile strength and maximum strain master curves under the test conditions of - 20 ~ 70 °C, 0.5 mm/min ~ 500 mm/min ...

Characterization of uncured and cured hydroxyl terminated polybutadiene prepolymer

2020
ABSTRACT Hydroxyl terminated polybutadienes < HTPB) are being used for the production of composite solid propel lants. Liquid hydroxyl terminated polybutadiene can be crossl inked with chain extension by the reaction of the terminal hydroxyl groups with the diisocyanate groups of isophorone diisocyanate < IPDI) and yield polyurethanes.
