Abstract
Rodrun 5000/Vectra B950 blends were obtained by direct injection moulding a t two injections rates. The blends were partially miscible and unreacted un der 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 th e blends led to a range of LCP materials with intermediate modulus and tens ile strength and slightly higher ductility.
