Poly(4-vinylpyridine)-poly(dimethylsiloxane) (P4VP-PDMS) block copolymers with various compositions were prepared by anionic polymerization. The 4VP block was quaternized with methyl iodide and reacted with 7,7',8,8'-tetracyanoquinodimethane (TCNQ), which is in both anion radical (TCNQ-') and neutral form (TCNQ°). The products were then characterized by 1H nuclear magnetic resonance and Fouriertransform infra-red spectroscopy, scanning electron microscopy and differential scanning calorimetry techniques. The electrical conductivities of processable and flexible fihns of these block copolymers were measured with the four-probe method and found to be as high as 10 .2 Scm -1. The optimal TCNQ ° doping for which the conductivities are highest were also determined
