Abstract
The bending phenomenon at the die emit is theoretically analyzed in the case of bicomponent polymer melt flow. The bending angle was derived from the melt elasticity difference of the two phase and determined as a function of the phase portion and the ratio of extrudate swelling. It was found that the exit bending angle increased with the ratio of extrudate swelling antral that the angle had a maximum when it was plotted against the phase portion. The maximum value increased with the ratio of extrudate swelling and shifted to the high value of higher elastic phase portion as the ratio of extrudate swelling increased. The interface shifting phenomenon at the die exit is also discussed briefly by geometrical analysis.
