Özet

Block copolymers of various compositions, consisting of poly(4-vinylpyridine) (P4VP) and poly(dimethylsiloxane) (PDMS) blocks, were prepared by anionic polymerization. These samples were modified by the addition of various amounts of iodine in solution. The electrical conductivities of the doped materials were measured by the four-probe method and were found to be as high as 10(-5) S cm(-1). The optimum ratio of iodine to pyridine which gave the highest conductivity was determined.
