Zusammenfassung:	PCT No. PCT/JP82/00091 Sec. 371 Date Dec. 1, 1982 Sec. 102(e) Date Dec. 1, 1982 PCT Filed Apr. 1, 1982 PCT Pub. No. WO82/03399 PCT Pub. Date Oct. 14, 1982.A nitrocellulose composition in the form of chips containing 50 to 80 wt % of nitrocellulose and less than 1 wt % of water is produced by adding to water-wetted nitrocellulose an organic solvent which dissolves nitrocellulose and polyurethane resin and is inert to isocyanate in an amount of 30 to 300 parts by weight based on 100 parts by weight of dry nitrocellulose, mixing, rolling or extrusion molding, drying at 30 DEG to 55 DEG C., and cutting. This composition is useful as nitrocellulose for magnetic tape binder.
