Abstract:
1. A method for improving moldability of a thermoplastic resin composition, said composition comprising a combination of a first polyetheretherketone and a second polyetheretherketone which have a melt viscosity different from each other, which comprises adding or mixing the first polyetheretherketone relative to or with the second polyetheretherketone in a weight ratio of about 50/50 to 1/99 as a ratio of the former/the later, and melt-kneading the resultant mixture, wherein the first polyetheretherketone has a melt viscosity of 150 to 1500 Pa·s at a temperature of 400° C. and a shear rate of 1216 s the melt viscosity ratio of the first polyetheretherketone relative to the second polyetheretherketone at a temperature of 400° C. and a shear rate of 1216 s
