摘要：
This work reports a simple and ecofriendly way of recycling polyethylene terephthalate (PET) waste. PET waste was glycolyzed using trimethylolpropane (TMP) giving tetra-functional glycolyzate, to prepare alkyd resin. 0.25% ZnOAc and the TMP to PET molar ratio of 12:1 at 220 °C produced the best yield of glycolyzate. The obtained glycolyzate was characterized by Fourier transform infrared spectroscopy (FTIR) spectroscopy, 1H and 13C nuclear magnetic resonance (NMR) and further used in the synthesis of alkyd resins. The properties of the prepared alkyd resins including acid value, the pencil hardness, chemical resistance and thermal stability, were investigated. The pencil hardness of the cured resins film is 3H, which is better than the commercial alkyd resin YF-155. Thermogravimetric analysis (TGA) exhibited polymer decomposition occurred above 160 °C. When compared to commercial coatings, Zanthoxylum bungeanum seed oil (ZSO)-based alkyd resin from postconsumer PET bottles has potential for commercial applications, and may even be superior in thermal and chemical resistance.
