Abstract

A process for the production of plasticised nitrocellulose in the form designated "semi-chips", comprises impregnating nitrocellulose flock while the latter is present in a stirred suspension in water, separating the plasticised nitrocellulose obtained from the suspension, and drying at a temperature not exceeding 60.degree. C. The novel nitrocellulose "semi-chips" and the novel apparatus to carry out the invention are also described.
