The rheological behaviour of liquid crystalline polymers differs considerably from that of ordinary polymers as well as of low-molecular-weight liquid crystals. The only theoretical approach which has reached a significant development is based on the rigid rodlike model of the polymer molecule. In spite of the crudity of the model, the theoretical predictions based on it prove able to qualitatively describe the most peculiar features of the observed rheological behaviour. A comparison between the relevant experimental peculiarities and the qualitative predictions of the theory is presented.

Abstract
The rheological behaviour of liquid crystalline polymers differs considerably from that of ordinary polymers as well as of low-molecular-weight liquid crystals. The only theoretical approach which has reached a significant development is based on the rigid rodlike model of the polymer molecule. In spite of the crudity of the model, the theoretical predictions based on it prove able to qualitatively describe the most peculiar features of the observed rheological behaviour. A comparison between the relevant experimental peculiarities and the qualitative predictions of the theory is presented.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
