The title polymer was obtained electrochemically by the reduction of 4,4'-bis(dibromomethyl)-2,2'-dimethoxybiphenyl under
very smooth conditions. The DSC and TG/DTG curves registered at four different heating rates showed that the polymer is stable
in air up to 150C, where smooth degradation starts. Above 300C, decomposition is fast and exothermic (ΔH= –323 J g–1) . The activation energy (1164 kJ mol–1 ) was determined by Ozawa's method.
