Rheological properties of multiblock ether-ester copolymers

The paper deals with development of the rheological properties of poly(ethe r-ester) elastomers, The various types of Elitels and effects of shear rate on viscosity and a comparison of the rheological properties of different g rades of Elitels have been included. The study were carried out by using MF I (CEAST), Capillary Rheometer MCR (Instron), and Bypass Capillary Rheomete r (Gottfert), The individual features and possibility to adapt their proper ties to particular processing methods that are achieved by hard segments br anches modification have been explained, Comparisons of other popular and c ommercially available TPEs were performed.
