The present invention is directed to a continuous process for producing a foamable celluloid product by introducing a solid component (comprising nitrocellulose, chemical blowing agent (CBA), stabilizer and alcohol) and a liquid component (comprising camphor and acetone) into a mixer/devolatilizer machine where the chamber is under atmospheric pressure and having significant overhead space. The chamber is comprised of two zones wherein the first zone has a temperature that is less than the second zone and at least one rotor comprising hollow, temperature-controlled arms having a tilted angle affixed to the rotors. The rotors of the mixer/devolatilizer machine act to mix the solid and liquid components under lower shearing forces, lower mechanical stress and longer residence times than those used by twin-screw extruders.

The present disclosure provides a polymeric composition including a thermoplastic polymer and an ionic liquid compound, wherein the ionic liquid compound improves the melt flow rate of the polymeric composition. The present disclosure also provides a method of preparing a polymeric composition with improved melt flow rate by mixing an ionic liquid compound with a thermoplastic polymer to obtain the polymeric composition. In some aspects, the polymeric composition includes a recycled polymer.

Methods for manufacturing, re-activating and using compositions including fibrillated parenchymal cellulose and activator are provided. The activator has a low molecular weight and is used to facilitate reactivation.

The present invention is directed to a process for making combustible foam celluloid munition parts having high aspect ratios, different densities or having an insert embedded into the foam celluloid munition part. The process for making such foam celluloid munition part requires pre-soaking dry particles of celluloid, placing the celluloid particles into a munition part mold, exposing the celluloid particles to high heat and pressure until the celluloid particles expand and fuse into the shape of the mold. Varying the density or the size of the celluloid particles used in the process produces munition parts having different densities. In addition, the placement of inserts into the particles prior to exposure to high heat and pressure produces munition parts having inserts that are useful for identification and tracking of such parts.

The present invention relates to an improved method for producing a colloidal nitrocellulose dispersion made compatible with a system of acrylic monomers polymerized with surfactants in a water-based system under pressure. The self-emulsifiable system of the present invention is characterized by the latex formed by the nitrocellulose suspension in an aqueous medium, with nanometric particles and homogeneity and, consequently, a greater covering and smoothing power, high adherence, high gloss, greater chemical and mechanical resistance, rapid drying, less water retention when used in paints, varnish and sealant compositions for coatings in the fields of graphic printing, such as flexography and rotogravure, lamination, nail polish, metal-mechanics, decoration, glass, leather, plastics, wood surfaces, compounds and mortars, decorative wall paints, textiles, paper coatings and car paint repairs, inter alia. Besides providing high-performance properties, the product according to this invention is environmentally friendly.
