Effect of Capillary Dimensions On Die Swell of Molten Polymers

Thanh, Dang Huu 01 1900 (has links)
<p> The effect of capillary dimensions on the die swell of molten polymers is investigated. Low and high density polyethylene, polypropylene, polystyrene are used to make investigation It is found the die swell decreases vii th L/D. The plot of die swell index (d/D) vs. L/D has the shape of anexponential decay curve. </p> <p> Bagley's decaying equation is used to fit the data. The effect of Deborah number on die swell phenomenon is also studied. 'I'he relationship between the recoverable shear strains of infinitely long capillary and the one with dimensions ratio L/D is obtained. This relationship could be used to estima te the die swell of short capillary from its value at equilibrium and polymer characteristics. </p> / Thesis / Master of Engineering (MEngr)
