Method of producing a conductive masterbatch |
| abstract |
Disclosed is method for producing a conductive masterbatch comprising a polyamide and conductive carbon black, the conductive carbon black being present in the form of at least one agglomerated particle having a major axis of 20 to 100 µm, wherein the number of the agglomerated particle(s) is 1 to 100 as observed under an optical microscope with respect to a contiguous area of 3 mm 2 , the method comprising: (1) feeding a polyamide to a twin-screw extruder or kneader, followed by melting of the polyamide to obtain a molten polyamide; and (2) adding conductive carbon black and optionally an additional amount of a polyamide simultaneously to the molten polyamide in the extruder or kneader, followed by melt-kneading of the resultant mixture to obtain a conductive masterbatch. |
