Abstract (en)

[origin: WO9902607A2] Blends of thermotropic liquid crystalline polymers and unfunctionalized poly(phenylene oxides) in which the dispersed phase domain size is relatively small can be made by melt mixing the two types of polymers. These blends have good physical properties and can be used as molding resins.
