RHEOLOGICAL PROPERTIES OF PLASTICIZED DIACETYL CELLULOSE SOLUTIONS
Abstract
The method of rotational viscozymetry was used to study the rheological properties 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 nature and plasticizers content on the rheology of diacetyl cellulose solutions was analyzed.
