Prospective production ways of new heat-resisting materials based on polyimides

摘要

Article is devoted to receiving and research of materials on the basis of industrially made different kind of polyimide, including chemical modifying by reactivity polyfunctional compoundes. Existence in macromolecules of polyamide acids reactive carboxyl, amide and amino groups o, capable to interact with multifunctional monomeric and oligomeric modifiers, gives the chance of receiving the polyimide materials possessing properties of sewed polymers. As a result, provides improvement of strength properties and thermal characteristics of new polymeric materials for practical aimes.
