The purpose of this work was to study the effects of three green plasticizers H₂O, glycerol, and soybean oil, on the properties of bio-based BDIS polyamides. The BDIS polyamides synthesized from the following biomass monomers: 1,4-butanediamine (BD), 1,10-decanediamine (DD), itaconic acid (IA), and sebacic acid (SA). It is interesting to note that the amorphous BDIS (IA-80%) polyamide was changed from the glassy state to the rubbery state after water soaking and induced crystallization at the same time. The H₂O-plasticized non-crosslinked BDIS (IA-80%) polyamides can be very useful for the preparation of physical water gel. The glycerol- and soybean oil-plasticized BDIS (IA-80%) polyamides displayed excellent toughness. The plasticized BDIS (IA-80%) polyamides were characterized by Fouriertransform infrared spectroscopy (FTIR), differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), mechanical testing, and X-ray diffraction (XRD).
这项工作的目的是研究三种绿色增塑剂——水、甘油和大豆油，对生物基BDIS聚酰胺性能的影响。BDIS聚酰胺由以下生物质单体合成：1,4-丁二胺（BD）、1,10-癸二胺（DD）、衣康酸（IA）和癸二酸（SA）。值得注意的是，无定形BDIS（IA-80%）聚酰胺在水浸泡后从玻璃态转变为橡胶态，同时诱导结晶。水增塑的非交联BDIS（IA-80%）聚酰胺对于制备物理水凝胶可能非常有用。甘油和大豆油增塑的BDIS（IA-80%）聚酰胺表现出优异的韧性。通过傅里叶变换红外光谱（FTIR）、差示扫描量热法（DSC）、热重分析（TGA）、力学测试和X射线衍射（XRD）对增塑的BDIS（IA-80%）聚酰胺进行了表征。
