ABSTRACT
Card group-containing heterochain polyesthers were synthesized on the base of norbornene-type polycyclic bisphenols and diphenyldicarboxylic acid dichloroanhydride by the method of high temperature polycondensation. The obtained polymers are characterized by high heat- and thermal stability, are well soluble in chlorinated hydrocarbons and they form transparent films in solutions which are characterized by good mechanical and dielectric properties.
