Abstract: Polymer blends containing liquid crystalline polymers (LCPs) have received considerable interest in recent years. By blending LCPs with engineering thermoplastics, one can obtain so-called in-situ reinforced composites, in which the dispersed LCP phase forms highly oriented reinforcing fibers in the thermoplastic matrix during injection molding. LCP can significantly improve stiffness and strength of thermoplastics, and also can improve processing ability of thermoplastics by reducing viscosity. Studies related to determination of the relationship between mechanical properties and processing conditions are sparse and contradictory. The intention of this work is to quantitatively study the correlation between the mechanical properties of PC/LCP blends and processing conditions by using an injection molding machine fitted with velocity measurement transducer.
