Thermal and electrophysical properties of oligomeric salts of m-carboranedicarboxylic acid

A relationship between the thermal and electrophysical properties of the oligosalts of m-carboranedicarboxylic acid [ - OOC-CB 10 H 10 C-COO - Mt 2+ ] n (Mt = Cu, Mg, Ca, Zn, Cd, Pb) was established. The electric conductivity of the oligosalts heat treated at 500°C increases by 3-9 decimal orders; after pyrolysis at 900°C, the conductivity increases by 6-11 orders. Even after three years of storage, the conductivity of the pyrolysis products remains 3-9 orders higher than that of the initial oligosalts.
