Notes:
A series of AB diblock copolymers of poly(2-vinylpyridine) (P-2VP) and either polybutadiene or polystyrene were prepared in a nonpolar solvent at low temperature. Well-defined polymers with narrow molecular weight distributions were obtained and electron micrographs showed that these block copolymers form a well-separated two-phase morphology. Percolation of P-2VP domains could be achieved for samples with 40 and with 60 mol-% of P-2VP blocks. These samples were modified by addition of various amounts of iodine in solution and in the melt. Electric conductivities of the doped composites were determined by the four-probe method. The conductivities of the two phase systems were, in general, lower than that of P-2VP doped with I2.
