Reclamation of cured polysulfide-perchlorate propellants The waste cured propellant is reduced to a small particle size by passing it through a laboratory mill. It is then added to the extent of 20 percent of the total mixture to a normal mixture of propellant. The waste propellant re-liquefies to its precured state in the mixer by means of a molecular weight redistribution between the low molecular weight liquid polymer and the high molecular weight solid polymer. The reaction is complete in about 10 minutes.
