Synthesis of Azide-Functionalized Hydroxyl-Terminated Polybutadiene

Journal of Energetic Materials, 2016
This article reports ways to functionalize hydroxyl-terminated polybutadiene (HTPB) by azide groups to impart energetic properties to the polymer. Two different synthetic approaches were explored to synthesize azide-functionalized hydroxyl-terminated polybutadiene (azide-HTPB).

Properties of modified hydroxyl-terminated polybutadiene based polyurethane membrane

Journal of Membrane Science, 2002
Abstract One hydroxyl-terminated polybutadiene (HTPB) based polyurethane (PU) solution was prepared by reacting equal equivalent of 4,4-methylene diphenyl diisocyanate (MDI) and HTPB with 1,4-butanediol (BDO) as chain extender. The PU was then cast into membrane.

Single Step Synthesis of Nitro‐Functionalized Hydroxyl‐Terminated Polybutadiene

Propellants, Explosives, Pyrotechnics, 2013
AbstractThe paper reports the energization of Hydroxyl‐Terminated Polybutadiene (HTPB) by functionalizing explosophore NO2 over the HTPB backbone, resulting in the formation of conjugated nitro‐alkene derivative of HTPB. A convenient, inexpensive and efficient “one pot” procedure of synthesizing Nitro‐Functionalized Hydroxyl‐Terminated Polybutadiene ...

Characterization of hydroxyl-terminated polybutadiene

Polymer Bulletin, 1997
The 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.
