Does Oxidizer-Binder Bonding agents have effects on the oxidizer's impact sensitivity?
http://onlinelibrary.wiley.com/doi/10.1002/prep.201600123/fu...
Here is a paper presenting 3 compounds BA1, BA2, and BA3, and their effects on improving the adhesion between oxidizer particles such as AP and
binders such as GAP.
here is an image to better explain their study,
would this reduce the impact sensitivity of the oxidizer? since there are hydrogen bonds formed.
Edit, btw these compounds did improve oxidizer-binder adhesion, and this image is not from the study, its few screen shots ofthe study put together.

The binder may increase or decrease or even leave it at the same level...the H bonding is not always a sensitivity reducing factor...see primary
nitramines with very strong H bondings and secondary nitramines with weak H bondings...
For example:
O2N-NH-CH2-CH2-CH2-NH-NO2 will be very sensitive and denser because of H bondings...
while the isomeric
CH3-N(NO2)-CH2-N(NO2)-CH3 will be sensitive (but less) and less dense because of weaker H bondings.
Also traces of organic material increases sometimes dramatically the sensitivity of HE oxidizers...this is true with Ammonium nitrate, perchlorate,
nitroformiate, dinitramide.
So the impact of the binder onto the sensitivity is very hard to predict even if the molecular structure of the interaction is fully known by 3D
modeling or X-rays...
