Am. Stolin et Vi. Irzhak, STRUCTURALLY NONUNIFORM FLOW REGIMES IN-P ROCESS OF POLYMER FIBER FORMATION, Vysokomolekularnye soedinenia. Seria A, 35(7), 1993, pp. 20000902-20000904
Regimes of polymer melt flow in the process of fiber formation are ana
lyzed. A possibility of structural non-uniform character of the flow i
s shown. This character of the flow appears as a falling branch in rhe
ological curves, i.e. as a superanomaly of viscosity. The non-uniform
crystalline structure is shown to be a result of the non-uniform chara
cter of the flow on the example of polyethylene.
