| Abstract: |
| The elastic behaviour and mechanism of polymers in flow during extrusion were discussed.A formula to calculate the elastic strain energy and the shear elasticity was proposed.The data of the tread from the cappillary rheometer were compared with those from the model in the published papers. |
