    Synthesis and Characterization of Thermoplastic Poly(Ester Amide)s Elastomer (TPEaE) Obtained from Recycled PET

    Zhi-Yu Yang, Yi-Ling Chou, Hao-Chun Yang, Chin-Wen Chen*, Syang-Peng Rwei*

    Journal of Renewable Materials, Vol.9, No.5, pp. 867-880, 2021, DOI:10.32604/jrm.2021.014476

    Abstract A series of thermoplastic polyester elastomer (TPEE) and thermoplastic poly(ester amide)s elastomer (TPEaE) copolymers were obtained by depolymerizing PET (polyethylene terephthalate) by which the waste PET can be efficiently recovered and recycled into value-added products from a practical and economical point of view. The structure of TPEE and TPEaE was identified using nuclear magnetic resonance (NMR) and Fourier transform infrared spectroscopy (FT-IR). Differential scanning calorimetry (DSC) data showed that the melting temperature (Tm) decreased with the amide content increased. The glass transition temperature (Tg) was increased as introducing the amide group, and the formation of amide-ester and amide-amide hydrogen bonds… More >

    Synthesis and Properties of Thermoplastic Polyisocyanurates: Polyisocyanuratoamide, Polyisocyanurato(Ester-Amide) and Polyisocyanurato (Urea-Ester)

    Journal of Renewable Materials, Vol.8, No.4, pp. 397-403, 2020, DOI:10.32604/jrm.2020.08912

    Abstract It has been proved that introducing isocyanurate into polymer chains could improve the flame retardancy of polymers. We describe in this work the synthesis and the thermal property study of three thermoplastic polyisocyanurates, which are polyisocyanuratoamide (PICA-6), polyisocyanurato(ester amide) (PICEA-6) and polyisocyanurato(urea ester) (PICUE-6). These polymers show similar and improved thermal stability with the existence of isocyanurate rings. PICA-6 is more crystalizable than the rest two and the melting temperature is found to be around 240°C but it still crystalizes slowly. For PICEA-6 and PICUE-6, only glass transition can be observed on the DSC traces. The glass transition temperature follows… More >
