  • RECYCLING OF EPOXY RESINS AND POLYMER COMPOSITE MATERIALS ON THEIR BASES (review)
    In this work the most common methods of recycling of carbon and glass composite materials based on epoxy resins are discussed. Recycling of thermosetting polymers and materials on their bases are one of the most difficult questions in modern chemistry of composite materials. This class of materials cannot be melted by heat and re-molded, since there are many strong cross-linking bonds in them. Even more difficult is recycling of polymer composite materials, which are multi-phase materials, which contain fillers, fibers and cured polymer matrix.
    Keywords: recycling, thermosetting compositions, epoxy compositions, polymer composite materials.

  • RENEWABLE SOURCES OF RAW MATERIALS FOR EPOXY OLIGOMERS CHEMISTRY (review)
    In this paper the possibility of producing epoxy resins with epichlorohydrin prepared from renewable materials and vegetable oils instead of synthetic polymers from natural gas, coal and oil feedstock are discussed. The requirement to use renewable raw materials to obtain the final product, including epoxy oligomers, instead of the exhausted, is very relevant. As a raw material for producing epoxy oligomers may be used various petroleum resins and vegetable oils, and the process for producing such epoxy oligomers is epoxidation of these resins and oils.
    Keywords: epichlorohydrin, epoxy oligomers, petroleum resins, vegetable oils, epoxidation.

  • THE DIFFRACTION ANALYSIS OF THE WHITE X-RADIATION ON CRYSTALS BY EWALD STRUCTURE AT DIRECT POLAR FIGURES CONSTRUCTION
    The diffraction analysis of a white X-radiation on twirled crystal lattices with application of Ewald structure is carried out. Assay values are applicable in crystal structure researches in which twirl of crystals is applied, in particular, at construction of direct polar figures. Ewald structure studies communication between parametres of X-ray shooting and the maintenance of direct polar figures of crystals. It is shown, that for construction of a crystal direct polar figure with application of a white X-radiation it is not required to any additional information on a crystal structure of an investigated material
    Keywords: continuous roentgen spectrum, white X-radiation, X-ray crystal analysis, crystal structure, Ewald structure.
