3.The result shows that the extensional flowing of the melt occurs in convergent die resulting in intense entrance elastic effect and distinct extrusion swell.
4.The results show that the extensional flow of melt in convergent die results in intense entrance elastic effect and distinct extrusion swell in conical die with different angles.
6.In this paper the flowability,die swell and melt fracture of ACR/PVC blends prepared from three types of acrylate copolymers and polyvinyl chloride have been studied.
