Abstract
A double base propellant having plasticizer and ballistic modifiers unifoy dispersed therein is formed by using high speed, high shear techniques. The method of uniformly incorporating plasticizers and ballistic modifiers in a solventless process for preparing nitrocellulose is accomplished by forming a slurry of nitrocellulose under high shear, high speed mixing, adding the plasticizers and modifiers thereto and recovering the propellant.
