  • 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.
