PROCESS FOR PRODUCING POLYMER MATERIALS
This invention relates to the radiation chemistry and high-energy chemistry technologies for the production, by heat-and-radiation treatment of workpieces, of enhanced-performance polymer materials, in particular, of polytetrafluoroethylene (PTFE) and other sorts of fluoroplastics used in various industries. Specifically, it relates to treating workpieces by high-energy ionizing radiation at a temperature strictly higher than the polymer crystalline phase melting point in an anoxic environment. The treatment is done via a pulsed linear electron accelerator generating ionizing radiation until an absorbed dose of 0-500 kGy is achieved. During the irradiation process, the polymer temperature is reduced by not more than 0.5 C./10 kGy, and subsequent to the ionizing radiation treatment, the polymer is heat treated. Alpha radiation, gamma radiation, electron radiation, irradiation with high-energy protons and neutrons, radiation from natural sources are used for the treatment. By this treatment method, physical and mechanical properties of the material are improved and consistency and programmability of the physical and mechanical characteristics are provided. 7 sub-claims.
