ELECTROCONDUCTIVE MASTERBATCH AND RESIN COMPOSITION INCLUDING THE SAME

Title:

ELECTROCONDUCTIVE MASTERBATCH AND RESIN COMPOSITION INCLUDING THE SAME

Document Type and Number:

WIPO Patent Application WO/2006/049139

Kind Code:

A1

Abstract:

An electroconductive masterbatch, characterized in that it comprises at least one electroconductive filler selected from carbon black and carbon nanotube, a polyamide resin, and a copolymer having, at least as monomer units, a vinyl monomer having a functional group being reactive with the above polyamide resin and styrene, wherein the content of the above electroconductive filler is 10 to 40 mass %; and a resin composition including the above masterbatch. The above electroconductive masterbatch is good in kneadability, processability and the dispersibility of an electroconductive filler such as carbon black, and exhibits stable electroconductivity, even when the masterbatch contains a large amount of an electroconductive filler such as carbon black.
