Elastomeric modified cast double base (EMCDB) propellant, which has good mechanical properties and plateau burning effect, was successfully prepared by granule casting process.

Elastomeric modified cast double base (EMCDB) propellant, which has good mechanical properties and plateau burning-effect, has been first successfully prepared by granule-casting in China.

Cast nylon modified with laurolactam was prepared by activated anionic copolymerization under the adiabatic condition. Its mechanical properties were studied.
