Blends of a thermotropic copolyester and a thermotropic copoly(ester–amide): structure and mechanical properties

Rodrun 5000/Vectra B950 blends were obtained by direct injection moulding at two injections rates. The blends were partially miscible and unreacted under the processing conditions used. Higher orientations and properties were obtained at the lower injection rate due to the higher overall orientation obtained. The produced orientation and the negative volume of mixing of the blends led to a range of LCP materials with intermediate modulus and tensile strength and slightly higher ductility.
