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.
The effect of molecular structure of polymer to anti-swell ability are studied by analysing clay stabilization capabilities investigated.
通过防止泥页岩水化膨胀的粘土稳定性能研究，讨论了它们的分子结构对抑制性的影响。

The variation of swell stress shows that with the increase of swell stress, the diffusion of water in GCL will be restrained, and water penetration stopped, so GCL has a water-proofing effect.
