Rheology, viscoelastic measurements and morphological aspects of blends of a commercial liquid crystalline polymer (LCP) and a polyarylate of bisphenol A (PAr) are presented. Viscoelastic results reveal incompatibility between the components and in the case of 60 LCP/40 PAr blends the physical properties are different, depending on the mixing method. This is attributed to the relationship between rheology, morphology and properties. The influence of the composition and the draw ratio on the storage tensile modulus is also studied.
