The structure and temperature dependence of resistance and thermal stability of undoped aminocontained polyarylenes (polyaniline, poly-ortho- and poly-meta-aminophenoles) have been investigated in the range of $T=293$-773 K. It is found that the studied samples are amorphously-crystalline materials with contents of crystalline phase 23-41\% and crystallites dimensions 1.0-2.5 nm. It is manifested that the character of polymers resistance change with temperature is attributed to organic semiconductors. A change of inclination of resistance temperature dependence is compared with main extrema of thermogravimetrical curves possibly entailed by transformations of molecular structure and beginning of polymers thermal decomposition.
