    Abstract: PROBLEM TO BE SOLVED: To obtain a partial aromatic copolyamide continuously producible by a simple method without causing a problem by cross linking at all, having improved processing performance, heat distortion resistance and excellent mechanical characteristics. SOLUTION: This copolyamide comprises (A) a unit derived from terephthalic acid and hexamethylenediamine, (B) a unit derived from ε k-caprolactam and (C) a unit derived from adipic acid and hexamethylenediamine as essential constitutent components in which the constituent components A, B and C exist in the interior of the pentagon formed by vertexes X1 to X5 in a three component diagram. The vertexes are as follows. X1 : the unit A 40wt.% and the unit C 60wt.%. X2 : the unit A 60wt.% and the unit C 40wt.%. X3 : the unit A 80wt.%, the unit B 5wt.% and the unit C 15wt.%. X4 : the unit A 80wt.%, the unit B 20wt.%. X5 is the unit A 50wt.% and the unit B 50wt.%.

    Abstract: PROBLEM TO BE SOLVED: To provide a partially aromatic copolyamide continuously producible by a simple process without causing any problem by crosslinking and having improved processability and thermal deformation resistance and excellent mechanical properties. SOLUTION: This partially aromatic copolyamide has a relative viscosity of 2.2-5.0 and contains (A) 40-90wt.% of a unit derived from terephthalic acid and hexamethylenediamine, (B) 0-50wt.% of a unit derived from ε-caprolactam and (C) 0-60wt.% of a unit derived from adipic acid and hexamethylenediamine as essential constituent components. The component B and/or C accounts for >=10wt.% of the total units and the copolyamide has a triamine content of
