RHEOLOGICAL PROPERTIES OF PLASTICIZED DIACETYL CELLULOSE SOLUTIONS

46-51The method of rotational viscozymetry was used to study the rheological prop-erties of diacetyl cellulose solutions in cyclogexanone in the presence of plasticizers – diesters of phtalic and 4-nitrophtalic acids. Given systems were shown to close to Newtonian fluids. Activation parameters of the viscous flow regime were calculated. The influence of na-ture and plasticizers content on the rheology of diacetyl cellulose solutions was analyzed.

Key words: diacetyl cellulose, nitrosubstituted plasticizers, dibutylphthalate, rheology, dynamic viscosity, viscous flow activation entropy
