    Description / Table of Contents: Poly(benzimidazole) und Poly(amidobenzimidazole) auf Basis unterschiedlicher Tetramine, Diphenylate von Dicarbonsäuren sowie ε-Caprolactam und Diaminen wurden untersucht. Für die Synthese wurden 3,3′-Diaminobenzidin oder aromatische Tetramine mit Methylen-, Sauerstoff- oder Sulfongruppen zwischen den Benzenringen eingesetzt. Die erhaltenen Polymere sind thermostabile, lösliche Produkte mit ausreichend hohen Molekülmassen.
    Notes: The poly(benzimidazole)s and poly(amidobenzimidazole)s produced on the base of different tetramines, diphenylate of dicarboxylic acids, and ε-caprolactam or diamines are investigated. In the synthesis were used 3,3′-diaminobenzidine or aromatic tetramines containing methylene, oxygen, or sulfon groups between the benzene cycles. The produced polymers are thermostable, soluble, and have high enough molecular weights.

    Description / Table of Contents: Poly(benzimidazole) und Poly(amidobenzimidazole) mit Schwefelatomen oder Sulfongruppen in der makromolekularen Kette wurden synthetisiert und untersucht. Als Ausgangsmonomere wurden schwefelhaltige aromatische Tetramine, Diamine und Dicarbonsäuren eingesetzt. Die erhaltenen Polymere haben ausreichend hohe Molekülmassen und sind in den üblichen organischen Lösungsmitteln leicht löslich.
    Notes: Poly(benzimidazoles) and poly(amidobenzimidazoles) containing sulfur heteroatoms or sulfon groups in the macromolecular chain were synthesized and investigated. Sulfur-containing aromatic tetramines, diamines and dicarboxylic acids were used as the initial monomers. The produced polymers have sufficiently high molecular weights and are well soluble in usual organic solvents.
