    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

    Abstract: Disclosed is a method for producing a polyamide containing titanium dioxide pigments. Said method is characterized by the fact that titanium dioxide pigments are dispersed in an initial mixture containing water and caprolactam by means of a device comprising a dispersion chamber, a disk-shaped rotor that is disposed inside said dispersion chamber, a stator that is provided with radial openings, is arranged within the dispersion zone of the dispersion chamber, and is connected to the rotor, a substance inlet located on each side of the rotor, preferably with a respective axial duct section such that the two flows of substance are combined in the peripheral edge area of the rotor disk, and a product outlet which is placed on the outer edge of the dispersion zone of the dispersion chamber, by feeding the titanium dioxide pigments to the dispersion chamber through one of said substance inlets while feeding the initial mixture containing water and caprolactam to the dispersion chamber through the other of said substance inlets, whereby a product mixture containing water, caprolactam, and the used titanium dioxide pigment is obtained via the product outlet, and the product mixture is polymerized so as to obtain a polyamide containing titanium dioxide pigments. Also disclosed are polyamides obtained according to the inventive method and the use of such polyamides as a masterbatch.
