Abstract

Polydibromoacetylenes were synthesized under different polymerization conditions and with Al-Ti coordinative catalysts. For the characterization of the polymers and for the study of the correlation between polymerization conditions and properties of the polymers, 13C MAS NMR, ESR and UV spectroscopies were used. The electrical conductivity of the polymers was measured in dependence on temperature. The energy gap decreased with increased crystallinity. As compared to polyacetylene the conductivity of polydibromoacetylenes was lower, but the stability against oxygen was higher. The polydibromoacetylenes were thermal stabile up to 200°C.
