Title:
PRODUCTION OF CONDUCTIVE RESIN COMPOSITION AND CONDUCTOR
Document Type and Number:
Japanese Patent JP3472406
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a process by which a conductive resin composition containing carbon black and having excellent surface smoothness and stable conductivity is produced while attaining significantly improved productivity.
SOLUTION: A conductive resin composition comprising a thermoplastic resin and conductive carbon black is produced through continuous kneading/ extrusion by a process which comprises kneading part of the resin together with the carbon black in the upstream region of the barrel in a kneading extruder to produce a master batch, subsequently introducing the remainder of the resin in the downstream region of the barrel, and kneading the resultant mixture to dilute the master batch.
