摘要：

The paper deals with development of the rheological properties of poly(ether-ester) elastomers. The various types of Elitels and effects of shear rate on viscosity and a comparison of the rheological properties of different grades of Elitels have been included. The study were carried out by using MFI (CEAST), Capillary Rheometer MCR (Instron), and Bypass Capillary Rheometer (Gottfert). The individual features and possibility to adapt their properties to particular processing methods that are achieved by hard segments branches modification have been explained. Comparisons of other popular and commercially available TPEs were performed.
