【Abstract】 The dynamic rheology research has unique advantages in the determination of polymer viscoelastic properties. It is an effective method for the investigation of the morphology-structure relationship for multi-component polymer blends. The theories and applications to multi-component polymer blends of the dynamic rheology were involved in this paper. The dynamic rheological behaviors of polymer blends according to the dynamic rheology theories, and the application of the dynamic rheology to the blends′ viscoelastic behavior have been analyzed. Especially, the influence of phase-separation, morphology and molecule weight distribution, etc. on the dynamic rheological behaviors of the multi-component was described in detail.更多还原
