Abstract
Electrically conductive polymeric compositions are obtained by incorporat crown ether complexes of TCNQ salts in a polymer selected from the class consisting of polycarbonates and poly(alkyl alkacrylates). The compositions can be formed into semiconductive films useful in the fabrication of e.g. thermoresistors and electronic devices.
Claims7
An electrically conductive polymeric composition consisting essentially of a polymer selected from the class consisting of polycarbonates and poly(alkyl alkacrylates) wherein the alkyl radicals have from one to 10 carbons and, dispersed therein, an effective amount of a crown ether complex represented by the formula:
- [(OA).sub.x.M].sup.+m [TCNQ].sub.m [TCNQ].sub.n .degree.
- wherein m is 1 or 2, n is 0 or 1, TCNQ is 7,7,8,8,-tetracyano-p-quinodimethane, M is selected from the group consisting of lithium, sodium, potassium, rubidium, lesium calcium, strontium, and barium, and (OA).sub.x is a macrocycle wherein x is an integer from 4 to 10, 0 represents oxygen and A is a bivalent hydrocarbon radical having from 2 to 8 carbon atoms in which the free valences are separated by two carbon atoms.
