摘要：

A polymer, poly(2,5-trimethylene benzimidazole), the first of a new family of nonsymmetrical polymers, was synthesized via an eight-step synthetic route. The polymer, obtained by melt polymerization, is amorphous and in its neutral form behaves as a moderate insulator. It forms 1:1 HCl adducts. When cast from formic acid solution, it forms 1:1 formic acid adducts. the acid adducts are semiconductors with resistivities in the 10**6-10**8 ohm-cm range. Space-charge effects are generated in the adducts as carrier mobility rises.
