## Abstract It is known that polyethylene extruding from a capillary viscometer does not attain a steadyβstate output rate immediately following a pressure imposition. The time dependence of output rate was studied quantitatively, and under some extrusion conditions was found to be of surprisingly
The estimation of the compatibility of different pairs of polymers can be based on capillary viscometry data for ternary polymer-polymer-solvent systems using mathematical models based on the slope of the Huggins equation (β¬b) and Huggins constant (β¬kΠ). In this study, the compatibility of binary mi
