二苯甲酰氯（SMCl）和亚芳基砜醚二胺（SED）。在溶液聚合中，研究了环氧丙烷（PO）、氯化锂（LiCl）/氢氧化锂（LiOH）和三乙胺（TEA）等酸受体对聚酰胺分子量的影响。研究了甲基取代和未取代芳砜醚二胺对聚酰胺分子量和热性能的影响。用溶液粘度、元素分析、热重分析、差示扫描量热法和X-射线衍射等方法对所制备的聚酰胺进行了表征。比较了由SPCl和SED与由SMCl和SED制备的聚酰胺的物理和热性能。
dibenzoyl chloride (SMCl), and arylene sulfone ether diamines (SED), by solution and interfacial polymerization techniques. In solution polymerization, the effect of various acid acceptors such as propylene oxide (PO), lithium chloride (LiCl)/lithium hydroxide (LiOH), and triethylamine (TEA) on molecular weight of the polyamides was studied. The effect of methyl substituted and unsubstituted aromatic sulfone ether diamines on molecular weight and thermal properties of polyamides was also studied. The polyamides prepared were characterized by solution viscoSity, elemental analysis, thermal gravimetric analysis, differential scanning calorimetry, and x-ray diffraction. Physical and thermal properties of polyamides prepared from SPCl and SED were compared with the polyamides prepared from SMCl and SED.
