A novel anthracene, pyridine and 1, 2, 3-triazole containing diamine was synthesized by copper catalyst 1, 3-dipolar cycloaddition of azides and alkynes groups (Click reaction). A series of polytriazoleimide (PTAI) nanocomposites were successfully prepared by condensation polymerization between the synthesized diamine monomer and commercially available pyromellitic dianhydride with different weight percentage of titanium dioxide (TiO 2 ). The structure of the monomer and polymer were confirmed by the fourier transform infrared and nuclear magnetic resonance spectroscopy. The synthesized PTAI is readily soluble in common polar solvents. The PTAIs naocomposites exhibited high thermal stability, the temperature corresponding to a 5% weight loss in the range of 4958C-5558C, excellent flame retardancy (char yield were found to be in the range of 48.

ABSTRACT:A new diamine containing 1,2,3-triazole ring was synthesized by the click reaction in the presence of Cu (I) catalyst.A series of novel polytriazoleimides (PTAIs) were synthesized using the prepared diamine by the conventional two-step thermal or chemical imidization method with commercially available aromatic dianhydrides. The chemical structure of the monomers and polymers was characterized by Fourier transform Infrared, 1 H nuclear magnetic resonance (NMR), and 13 C NMR spectral analysis. Solubility of the PTAIs was tested in various organic solvents. The glass transition temperatures of these PTAIs are in the range of 215-254°C. PTAIs exhibit low dielectric constant of 3.04-3.34 at 1 MHz, high thermal stability, and temperature corresponding to 5% (T 5% ) weight loss is in the range of 442-492°C. The flame retardance values (limiting oxygen index) are in the range of 38.4-40.5. The PTAI films exhibited good mechanical properties with tensile strength of 96.2-98.9 MPa, elongation to break of 9.8-12.6%, and tensile modulus of 2.5-3

“…The bulky poly aryl groups like naphthalene and anthracene caused elevated T g and good thermal and mechanical properties with better solubility in the organic solvents . Our already reported works show that if the polymer chain includes hetero aromatic rings like pyridine , triazole , quinoline , in the main chain, thermal stability will be very high. Inclusion of long and bulky multiple alkyl side chains impart extra solubility, toughness, flexibility, and good elongation even above 200%, that is, elastomeric properties in the polyimides but with inferior thermal and mechanical properties .…”

A new diamine monomer having ether and azomethine linkages in the long pendent group was synthesized. New polyimide was prepared by reacting the new diamine with BTDA and nanocomposites were prepared with silicon dioxide as nanofiller. SEM analysis shows a uniform distribution of the nanopowder in the polyimide matrix. TGA shows that the polyimide and nanocomposites have good thermal stability with the T10% values varying between 440 and 458°C. DSC analysis shows Tg values between 210 and 230°C. The neat polyimide shows high elongation at break and stretchability (260%) but low tensile strength. The nanocomposites of polyimide show lower elongation at break but have improved tensile strength. The chemically imidised polyimide shows good solubility in solvents like N, N‐dimethyl formamide, N, N‐dimethyl acetamide, and N‐methyl 2‐pyrrollidone. POLYM.
