organoplastics, polytetrafluoroethylene, fiber, Tanlon, IR-spectral analysis.

Today, composite materials based on polymer, reinforced by organic fibers in terms of production exceed steel, aluminum, cast iron and plastics due to their unique properties: high chemical resistance, low density (they are easier,than carbon fiber and fiberglass), ability to long-term accumulation of damage in the volume of the detail without formation of critical cracks. Great application find organoplastics based on the heat-resistant thermoplastic binders, one of the promising representatives of which are fluoropolymers, including polytetrafluoroethylene (fluoroplast-4), which is well-known for its exceptional resistance to the aggressive environments (alkalis, acids, petroleum products, organic and inorganic solvents), wide temperature range of the operation (4–533 K), low coefficient of friction and natural lubricity. Taking into account the foregoing, the development of new organoplastics, that are able to work in difficult conditions (at high loads and temperatures, under the effect of aggressive environments), including based on fluoropolymers, with improved operational characteristics is an urgent task for modern material science. In this article are given infrared spectra of organoplastics based on polytetrafluoroethylene, reinforced by polysulfonamide fiber brand Tanlon T700. It has been established, that with the addition of 5–20 wt.% exist interaction of chemical and physical nature between the components of the developed organoplastics. From the obtained data, it should be noted, that the greatest chemical interaction, both from the side of polytetrafluoroethylene and from the Tanlon fiber, is observed for the composite material, containing 20 wt.% of filler, while the given organoplastic is chemically unstable, because it contains new multiple bonds (cumulative , double, triple), as well as in it arise new Н-bonds of interpolymeric character.
