ABSTRACT:
A method for manufacturing crosslinked double base propellants which incls compounding the propellant with no more than 0.1 weight percent of a crosslinking catalyst, partially curing the propellant by a mild heat prior to extrusion until the energetic binder is plasticized but not crosslinked, and extruding the propellant in a ram extruder at a temperature from 120.degree. F. to 150.degree. F. before the crosslinking mechanism has become too advanced for extrusion.
