Abstract
New copoly(naphthoyleneimidobenzimidazoles) were synthesized on the ba sis of 1,4,5,8-naphthalenetetracarboxylic dianhydride, 5(6)-amino-2(p- aminophenyl)benzimidazole, and aromatic rigid-rod diamines. The streng th parameters of films based on these polymers increase sharply both i n the initial and in an oriented state if the material contains 20 - 4 0 mol % of rodlike fragments. The ultimate tensile strength of an orie nted film material based on a polymer containing 30 mol % diphenyl uni ts reaches 1.5 GPa with the elasticity modulus of 38 GPa.
