## Abstract A screw extruder and capillary dies of different length radius ratios were used to measure melt flow and end effects for three commercial polyethylene resins, two of low density and one of high density. The apparent melt viscosities of the low density resins decreased faster with increa
The condition which determines whether ash will cause fouling on heat transfer surfaces in p.c.-fired boilers is that the viscosity must lie between 0.1 and 10 MPa s. Ash under these conditions is stiff, exists in two phases and therefore exhibits a yield stress. A new type of rheometer consisting o
Mutual diffusion coefficients are measured for the ethylbenzene-polystyrene system for the temperature range of 115.5Β°-1780C and for concentrations as high as.70 wt-96 ethylbenzene. Experiments were carried out using a quartz spring sorption apparatus which was modified for hightemperature measureme
