Extrudate Swell Rheometer and Method of Using Same.

Abstract

Apparatus and methods for the measurement of the first normal stress difference of a polymeric solution by measurement of the extrudate swell, and for the measurement of the first normal stress difference of toxic fluids by measurement of the extrudate swell, and for accurately measuring smaller values of the first normal stress difference of polymeric solutions than possible with conventional available rheometers are described.
