| Abstract: | The blends of phenolphthalein Polyethersulfone (PES - C ) and a thermotropic liquid crystalline polymer (LCP ) were prepared using melting mixing method.Rheological and mechanical properties of the blends were investigated. It was shown that addition of LCP in PES-C resulted in marked reduction of melt viscosity and improved processibility. The Chadly impact strength of the blend containing 2. 5% LCP increased about 2. 5 times comparing with pure PES-C. The tensile strength, Young's modulus, fie-cural strength and fie-cural modulus of the PES -C/LCP blends were also improved on some extent. The morphology of these blends were also observed by SEM, and the relationship between the me chanical properties and the morphology of blends were discussed. |
