Abstract
The present invention provides a liquid-crystalline polymer blend which is obtained by combining liquid-crystalline polymer (A) which has a modulus of elongation of 20-32 GPa and a melting point measured by differential scanning calorimeter of 250-330° C. and liquid-crystalline polymer (B) which has a melting point measured by differential scanning calorimeter of equal to or higher than 190° C. and lower than 250° C., wherein the weight ratio of said liquid-crystalline polymer (A) to said liquid-crystalline polymer (B) is in the range of from 50:50 to 90:10. The liquid-crystalline polymer blend and the liquid-crystalline polymer blend composition comprising the same exhibit good mechanical properties such as modulus of elongation and good molding processability at low temperatures. The liquid-crystalline polymer blend and the liquid-crystalline polymer blend composition of the present invention are suitable for producing welded articles with high joint strength.
