Webphase behavior is indispensable. In 1988 Zachmann and collaboratorsg have shown an example of a PLC phase diagram. In contrast to phase diagrams of non-LC polymer systems, their diagram shows a fairly large number of phase regions and an overall complexity. One of the first known PLC series were the copolyesters Webthe phase transformation to a semi-crystalline phase and finally solidifies. A molten polymer thread may undergo phase transformation into semi-crystalline phase even at a temperature above the equilibrium melting point of the polymer when the take-up speed exceeds a certain critical value, this phenomenon is known as flow-induced (or stress-induced) …
