ABSTRACT:
A method of making pelletized nitrocellulose (PNC) includes preparing a lacquer, the lacquer comprising nitrocellulose (NC), ethyl acetate and ethyl centralite, the NC having a nitrogen content of at least about 12.2%; mixing the lacquer with an antisolvent to thereby emulsify the lacquer and form PNC; drowning the PNC with the antisolvent; and separating the antisolvent and ethyl acetate from the PNC.
