  "definition": "Cellulosics are thermoplastic resins manufactured by chemical modification of cellulose [(C6H10O5)n]. Included are: cellophane - regenerated cellulose made by mixing cellulose xanthate [ROCSSH] with a dilute sodium hydroxide [NaOH] solution to form a viscose, then extruding the viscose into an acid bath for regeneration; cellulose acetate - an acetic acid ester [CH3COOC2H5] of cellulose; cellulose acetate butyrate - a mixed ester produced by treating fibrous cellulose with butyric acid [CH3CH2CH2COOH], butyric anhydride [(CH3CH2CH2CO)2O], acetic acid [CH3COOH] and acetic anhydride [(CH3CO)2O] in the presence of sulfuric acid [H2SO4]; cellulose propionate - formed by treating fibrous cellulose with propionic acid [CH3CH2CO2H] and acetic acid and anhydrides in the presence of sulfuric acid; cellulose nitrate - made by treati",
