A method for manufacturing a conductive composition comprises blending a polymer precursor with a single wall carbon nanotube composition; and polymerizing the polymer precursor to form an organic polymer. The method may be advantageously used for manufacturing automotive components, computer components, and other components where electrical conductivity properties are desirable.

Electrically conductive compositions and method of manufacture thereof

Aromatic polyether polymers, illustrated by polyethersulfones, polyetherketones and polyetherimides, are prepared by a phase transfer catalyzed reaction between a salt of a dihydroxyaromatic compound and a substituted aromatic compound such as bis(4-hydroxyphenyl) sulfone, bis(4-hydroxyphenyl) ketone or 1,3-bis[N-(4-chlorophthalimido)]benzene or the corresponding derivative of toluene or diphenyl ether, or the analogous fluoro-, bromo- or nitro-substituted compounds. The phase transfer catalysts employed are those which are stable at temperatures in the range of about 125-250 °C. Particularly preferred phase transfer catalysts are the hexaalkylguanidinium and α,φ-bis(pentaalkylguanidinium)alkane salts and the corresponding heterocyclic salts.
