Název v původním jazyce

Preparation, characterization and thermal degradation study of poly(amide imide)s based on tri-component mixture of PMDA/BTDA, diamines and acid chloride

Popis výsledku v původním jazyce

A series of poly(amide imide)s (PAIs) having alternate (amide-amide) and (imide-imide) units (polymers 1-14 and 22-35), and random distribution of amide-imide linkages (polymers 15-21 and 36-42) were prepared by low temperature solution polymerization ofbenzene-1,2,4,5-tetracarboxylic dianhydride (PMDA)/benzophenone-3,3',4,4'-tetracarboxylic dianhydride (BTDA), diamines (cyclic and aromatic) and acid chloride in dimethylforamide. All the polymers were readily soluble in polar aprotic solvents with inherent viscosities in the range of 0.134-0.878. The process of cycloimidization of poly(amide amic acid)s (PAAs) to PAIs was investigated by TGA and FT-IR techniques at four different temperatures i.e., 175, 200, 225, and 260°C. The rate of cycloimidization was calculated by taking into account the theoretical weight loss (WT), obtained from [n x Mw(H2O)/Mw(RU)] W, where Mw (H2O) molecular weight of water, W weight of PAA taken for TGA, Mw (RU) the molecular weight of repeat unit of PAA, n
