Thermal Stability and Mechanical Properties of Organo-Soluble and Processable Polyimides for High-Temperature Materials

Muhammad Kaleem Khosa, Muhammad Asghar Jamal, Rubbia Iqbal, Majid Muneer et autres

A new series of organo-soluble polyimides with pendant groups of methoxy or methyl of azomethine diamine were synthesized through two-step process by chemical imidization. Such polyimides were tested for thermal and mechanical properties. Their thermal stability was studied in terms of temperature …

Synthesis and characterization of new soluble thermally stable poly(azomethine-ether-imide)s: discerning the possibility for high temperature applications

Rubbia Iqbal, Muhammad Kaleem Khosa, Muhammad Asghar Jamal, Sadia Ilyas et autres

A new series of polyimides was synthesized by the condensation of monomers (azomethine-ether diamine, DA-1 and DA-2) with pyromelliticdianhydride (PMDA), 3,4,9,10-perylenetetracarboxylic dianhydride (PD) and 3,3′4,4′-benzophenonetetracarboxylic dianhydride (BD). The structural explications of monomers and polyimides was conducted by FT-IR, 1H NMR and elemental …
