Abstract

Electronic conductive polymers such as polyacetylenes, polyanilines and polythiophenes, are not easy to process due to lack of tractability and solubility. Chemical modifications of the polythiophenes backbone have been utilized to improve the processibility.

Our goal is to synthesize and characterize 3-[oligo(dimethylsiloxane)]- thiophene macromonomers as precursors for potentially processible, conductive derivatives of polythiophene. The precursor will be used in the preparation of various poly {[3- oligo(dimethylsiloxane)]thiophene-co-3-methylthiophene} random copolymers. By increasing the chain length of the low glass transition (Tg) side chain, we hope to produce processible elastomeric material.

w-(Si-H)-DMS, 3-propenylthiophene (i.e. precursors for the macromonomers), and the macromonomer were characterized (as appropriate) by 'HNMR, SiNMR, C NMR, DSC, IR, UV-VIS, GPC, and GC-MS.
