Abstract
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.
