Title:
CONDUCTIVE COMPOSITIONS WITH COMPOSITIONALLY CONTROLLED BULK RESISTIVITY
Document Type and Number:
WIPO Patent Application WO2000068299
Kind Code:
A3
Abstract:
The invention relates to a method of making a conductive thermoplastic composition containing at least one dispersed phase polymer with a continuous phase polymer and at least one conductivity imparting agent wherein the bulk resistivity of the composition is at least partially determined by the particle size of the dispersed phase within the continuous phase. The thermoplastic composition preferably comprises a compatibilized blend of at least one polyphenylene ether resin, at least one polyamide resin, and at least one conductivity imparting agent, and optionally, one or more of impact modifiers, stabilizers, antioxidants, lubricants, and fillers.
