Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
86 words
IN A PROCESS FOR MAKING A PLASTISOL PROPELLANT COMPOSITION COMPRISING DISPERSING A FINELY-DIVIDED DISPERSION- OR PLASTISOL-GRADE ORGANIC POLYMER AND A FINELY-DIVIDED, INSOLUBLE OXIDIZER IN AN ORGANIC LIQUID PLASTICIZER WHICH DISSOLVES THE POLYMER READILY ONLY AT ELEVATED TEMPERATURE, THE IMPROVEMENT COMPRISING DISSOLVING A PORTION OF THE SAID POLYMER IN SAID PLASTICIZER TO FORM A GEL OF FLUID TO SEMISOLID CONSISTENCY AND THEN ADMIXING SAID OXIDIZER AND THE REMAINDER OF THE POLYMER WITH SAID GEL AT A TEMPERATURE BELOW THE SOLUTION TEMPERATURE OF THE POLYMER IN THE PLASTICIZER.
Claim 2
Dependent Claim
