Thermotropic main chain LC polymers represent a new and, with respect to their application, special family of high-tech plastic materials The stiffening in processing direction oriented mesogenic units in the main chain gives rise to an enormous self-reinforcement in the plastic part. Furthermore, thermal dilatation, distortion, and shrinkage of the LCP resin after processing is so small that geometrically complex, highly precise parts can be produced from these high performance materials, The extraordinarily low heat capacity of the melt leads to a very rapid solidification process, conserving exactly the shear and/or elongation induced orientation states of the stiffening mesogens, In the following contribution the flow behavior of a commercial LCP resin in uniaxial extensional now will be investigated, and the elongation-induced orientation stales in highly stretched LCP films will be determined by using birefringence measurements. Shear induced nucleation of defects were observed in squeeze flow between cross polarizers, and the line texture thereby developed in the melt was analyzed.
