تحضير وتشخيص بعض الأنواع الجديدة من البولي ايميدات الاروماتية التي تحتوي عناصر البروم والكلور والفسفور كمثبطات للهب ودراسة بعض خواصها الحرارية

Abstract

In this work a new aromatic polyimides flame retardant (Api) containing bromine, chlorine and phosphorus components of through the polycondensation of the different monomers from aromatic diamine(ABTB, ABAB ,BDBP) with different monomers from dianhydride (PMDA,BTDA) as materials. The monomers aromatic diamine (ABTB, ABAB ,BDBP) and new aromatic polyimides(Api1,Api2,Api3) flame retardant were characterized by using FT-IR and 1HNMR spectra. The study has thermal stability, and flame retardant of polymers prepared through the TGA technique and comparing their with aromatic Polyimides prepared (PIPM, PIBT) free component of inhibition and their solubility study.
