Abstract. The article is devoted to production and study of materials based on different kinds of industrially manufactured polyimides, including chemical modification of reactivity of multifunctional compounds. The presence of reactive carboxyl, amide and amino groups, capable to interact with multifunctional monomeric and oligomeric modifiers, in macromolecules of polyamide acids, gives the chance of receiving the polyimide materials possessing properties of polymers. As a result, we observe improvement of strength properties and thermal

characteristics of new polymeric materials for practical aims.

Key words: polyimide, geometrical parameters, structural characteristics, properties, modification, block copolyimides.
