Abstract

عملية تحضير بولي أميد PROCESS FOR THE PREPARATION OF POLYAMIDES الملخـــص يتعلق الكشف الحالي بطريقة إنتاج متعدد أميد يتمتع ببساطة التحكم في العملية، وانخفاض التحلل الحراري، وزيادة المرونة التركيبية. وبشكل أكثر تحديدًا، يتعلق الكشف بعمليات تحويل أملاح ثنائية الأمين وأحماض ثنائي الكربوكسيل إلى متعدد أميد في الحالة الصلبة دون مرحلة الذوبان، بواسطة تمييع ثنائي الحامض الصلب في غاز مميع. شكل. 1
