High energy materials are essential ingredients in both rocket and explosive
formulations. These can be vulnerable due to maltreatment. During gulf war, several
catastrophic accidents have been reported from their own payload munitions. The role of
energetic binders here was to wrap the explosive formulations to convert it into insensitive
munitions. With the aid of energetic binders, the explosive charges are not only protected
from tragic accidents due to fire, bullet impact, adjacent detonation, unplanned
transportation, but also form total energy output presumption.
The use of energetic binders in rocket propellants and explosive charges has been
increased after the Second World War. Inert binders in combination with energetic
materials, performed well as binders but they diluted the final formulation. Obviously the
total energy output was reduced. Currently, the research in the field of energetic polymers is
an emerging area, since it plays crucial role in insensitive munitions.
The present work emphasises on the synthesis and characterization of oxetanes,
oxiranes and polyphosphazene based energetic polymers. The thesis is structured into six
chapters. First part of chapter 1 deals with brief history of energetic polymers. The second
part describes a brief literature survey of energetic polymers based on oxetanes and oxiranes.
Third and fourth parts deal with energetic plasticizers and energetic polyphosphazenes.
Finally, the fifth part deals with the various characterization techniques adopted for the
current study and sixth part includes objectives of the present work. |
