Abstract
The preparation and properties of 2,5-dipicryl-1,3,4-oxadiazole (DPO), a thermally stable substitute for PEIN, are discussed. Results of short pulse shock tests on DPO are also given. (b) Standard exploding foil test parameters were used (0.051 mm thick mylar flyer). 12. The m.p. of high purity DPO after crystallization from acetone-methanol is 335°C.
