SYNTHESIS OF CONDUCTING H-TYPE POLYSILOXANE-POLYPYRROLE BLOCK-COPOLYMERS

Synthesis of a siloxane polymer with pyrrole end groups has been descr ibed. Electrochemical block polymerization of pyrrole through these en d groups has been achieved. Characterization of the electrolytic produ cts has been performed by means of scanning electron microscopy (SEM), differential scanning calorimetry (DSC), thermal gravimetry analysis (TGA) analyses and FT-IR studies. The effects of different dopant ions , namely, p-toluene sulfonic acid (PTSA) and tetrabutylammonium tetraf luoroborate (TBAFB), in electropolymerization and conductivities of th e corresponding block copolymers have been investigated.
