BDNPF/A is a useful energetic plasticizer, but mixed formal, which consists of BDNPF, DNPBF, and BDNBF, is anticipated to be better than BDNPF/A in chemically, thermally and economically. Last year, we successfully synthesized and characterized the mixed formal that has minimum contents of diformal.

The thermogravimetry (TG) analysis of the new mixed formal plasticizer shows an acceptable stability for practical applications. This new plasticizer is expected to be cheaper than the existing mixed formal because only one compound of starting material, DNP-OH, is required, DNB-OH will not be used for this process, and the yield of formalization reaction was increased from 75 % to more than 90%.

EnRI has successfully synthesized energetic polymer plasticizers namely; low molecular weight GAP and azido terminated GAP (GAP-A). These energetic polymer based plasticizers are structurally similar to binder matrix and resist the migration due to enhanced miscibility. Low molecular weight (Mw= 650 to 800 g/mole) GAP polymers have been

Plasticizers help in improving the mechanical properties of the composite matrix, especially the binder.1The conventional plasticizers usually have inert and stable carbonhydrogen-based backbone and are used in all kinds of applications.
