Resumo: The present study focuses on the optimisation of LCP/TP compatibilised systems. This study was essentially devoted to the influence of different LCP and compatibiliser contents on the final morphological, rheological and mechanical properties of the blends. Rheologically, we used both standard small amplitude oscillatory shear and large amplitude oscillatory shear (LAOS) experiments in order to improve the understanding of the mechanisms behind the mechanical reinforcement that might be helpful in the optimisation of liquid crystalline polymer and thermoplastic blends. The results revealed that LAOS, in particular, is highly sensitive to different morphologies and may be correlated with the effectiveness of compatibilisers, which is not surprising since the flow behaviour of LCPs is highly complex and non-linear, with lower non-linear characters obtained for those blends that showed a higher fibrillar formation and better mechanical properties.
