Abstract

تمت عملية تحلق البولي ايزوبرين الاصطناعي باستخدام ايثيل ألمنيوم ثنائي الكلوريد و ثلاثي كلورو حمض الخل )كوسيط ومساعد وسيط(. أدت عملية تحلق البوليمير المذكور إلى تشكل مركبات مختلفة أحادية، وثنائية، وثلاثية، ومتعددة الحلقات، حيث تمت دراستها باستخدام المطيافيات المعروفة مثل : مطيافية الأشعة تحت الحمراء (IR)، ومطيافية الطنين المغناطيسي النووي (NMR).

استخدم في هذا العمل مذيب جديد هو التولوين، ونظام تحريض جديد أدى إلى الحصول على مردود عالٍ وصل حتى 93% من البوليمير المحلق التام الذوبان في المذيبات العطرية و 7% فقط من الهلام الشبكي عديم الذوبان.

The cyclization of synthetic polyisoprene has been carried out using ethyl dichloride aluminium (Et AlCl2) and trichloroacetic acid (CCl3COOH) (as catalyst and cocatalyst). This cyclization produces different products with mono, or di, or tri, or more rings, which were achieved using spectroscopy methods such as IR and NMR.

In this work, the new incitation system and the toluene (as new solvent) have been used to obtain completely soluble polycyclic polymer in aromatic solvents with yields of 93% and insoluble lattice jell with yields of 7% only.
