polar groups of selected polymers with the surface of such particles, systems are
formed and they are metal-containing polymers (MP) that optimally combine strength,
heat and electrical conductivity, magnetic, catalytic and other positive features of
metals, with the advantages of high molecular compounds, such as an ease of
processing, small specific gravity, elasticity, chemical resistance, damping ability and
good processability of processing.
Often, MPs have not only additive features, but also a number of new qualities
acquired due to the synergistic effect, which the known materials lack. This
combination of properties makes it possible to count on the wide application of the MP
in the field of radio electronics, electrical engineering, instrumentation and
engineering, in the aviation, metallurgical and chemical industries.
In general, it can be concluded that MPs have a valuable set of technological and
operational properties that favorably distinguish them from other materials. The
application of MP helps to effectively solve many technical problems that are often
irrational, difficult or even impossible to solve using traditional materials and methods.
This attracts more and more attention of researchers, designers and technicians, as well
as consumers [3].
There are a large number of convincing examples of their application in various
branches of the economy. Great experience in effective use was acquired in the field
of new developments and designs of friction units (slide bearings, gear and chain
drives, sealing devices, etc.), in the form of adhesives for repair and restoration works
and as a skin for aviation.
Metal-containing polymers are a promising class of PCM, which has improved
running ability compared with the closest analogues. Today, they have advantages
according to physical and mechanical properties, while maintaining fire resistance and
corrosion resistance, which is inherent in polymers, due to which the technical and
economic effectiveness of MP application is beyond doubt. The future, of course, is
behind polymeric composite materials, an important place among which will be
occupied by metal-containing polymers.
However, analysis of the literature shows that the existing MPs can not meet the
needs of the industry for a number of indicators, especially as materials operating under
harsh conditions at elevated temperatures. That is why research aimed at finding
rational compositions for work in such conditions is relevant for modern materials
science.
Development of technology for recycling metal-containing polymers. Today,
the significant development of technology favored the expansion of the use of thermo-
and heat-resistant polymers, characterized by long-term availability in a wide range of
temperatures, high strength properties, resistance to deformations and exposure to
corrosive media. Such polymers include the aromatic polyamide phenylone (APP), a
