The variation of viscosity of various polymer melts under constant shear rate conditions has been investigated using a biconical viscometer, a cone-plate viscometer, and a capillary rheometer. The validity of the biconical viscometer edge-zone correc

Extensive tests on unmasticated and masticated smoked sheet samples in the shearing-cone and Williams plastometers are reported. These constitute a preliminary survey of the behavior of these materials during shearing at various rates and for various

Instruments expected to give results characteristic of the various classes of plastometer have been compared in a number of respects. The Dillon extrusion plastometer, shearing cone rotation plastometer, and Williams compression plastometer, were com

The temperature rise that occurs on shearing rubber at high rates in the shearing-cone plastometer has been measured and shown to be about double that which is to be expected from simple theoretical considerations. This discrepancy is apparently due

An investigation into the effect of fillers on the flow properties of rubber stocks is described. It is shown that rubber stocks containing fillers soften on working and stiffen on standing, and these changes are associated with the breaking down and

Earlier dimensional analyses which established a relationship between the weight W0 of a very slowly formed (`static') drop and surface tension have been extended to rapidly formed drops of viscous liquids. ΔW/γR would be expected to be a function

Measurements have been made of the viscous resistance experienced by a solid sphere moving through a non-Newtonian liquid (poly-iso-butylene solution) which is simultaneously being sheared in a direction perpendicular to the line of motion of the par

The results of an experimental investigation of the rheologioal properties of dilute suspensions of rigid spheres 100μm in diameter in non-Newtonian pseudoplastic liquids are reported. The shear flow properties of suspensions in a solution of polyis

Following up earlier work on the subject, experiments are reported showing that the deterioration of the surface resistivity of ebonite caused by a particular quantity of light increases with decreasing intensity of illumination, and from the results
