摘要: Development of a method degradation poly(ethylene terephthalate) (PET) wastes for the preparation materials synthesis and modification epoxy resins, development characterization resins so prepared, optimization composition modified with recycled were goals this work. Therefore, conditions required strong waste PET by glycolysis reaction chosen. Glycols different length alkyl chain tested. Composition structure products determined GPC spectroscopic methods (i.e. FT-IR, 1H-NMR, 13C-NMR). Next, used as polyhydroxylic reagents their epichlorohydrin. Bis(2-hydroxyalkyl)-terephthalate was model compound. The applied in compositions Bisphenol A-based low-molecular-weight resins. It found that led to improvement tensile flexural strengths, hardness, thermal stability. Better results obtained longer fragments. incorporation alkylether chains from not only increased water absorption but also improved chemical stability against 10% HNO3, 75% H2SO4, ethyl acetate.
