Double Hydroxide

Aiming to develop a multi-functional flame retardant for epoxy resins, a novel bio-based eugenol derivative (SIEPDP) was synthesized, and was used to modify Mg–Al layered double hydroxide (SIEPDP-LDH). This modified SIEPDP-LDH was used as a novel nanoflame-retardant for bisphenol epoxy resins and compared with unmodified pristine LDH.

A novel chiral poly(amide imide) containing L-alanine was synthesized by direct polycondensation reaction of newly synthesized N,N’-(4,4’-diphthaloyl)-bis-L-alanine diacid with 4,4’-diaminodiphenyl ether in a medium consisting of N-methyl-2-pyrrolidone (NMP), triphenylphosphite (TPP), calcium chloride (CaCl2), and pyridine. The new chiral diimide-diacid monomer was synthesized by direct reaction of 3,3’-4,4’-Biphenyl tetracarboxylic acid dianhydride with L-alanine in acetic acid under refluxing conditions. The resulting compounds were obtained in quantitative yields and high purity. The synthetic diacid monomer was characterized by elemental analysis,1H-NMR spectroscopy, FT-IR techniques and specific rotation, the obtained polymer was characterized by FTIR techniques, specific rotation and solubility testing.

AbstractComposites from some novel polyimide and commercial epoxy were prepared aiming to improve the thermal behavior of epoxy resins. Two diamines namely 4-4'-diamino-4''-hydroxytriphenyl methane (DHTM) and 4-4'- diaminotriphenyl methane (DTM) were synthesized by reacting aniline and aldehydes according to a reported method. The synthesized diamines were blended with commercially available epoxy 1, 4-butanedioldiglycidylether (BDDE) to synthesize model epoxy amine networks which were compared with polyimideepoxy composites. The polyimides were synthesized by reaction of these diamines with aromatic anhydride namely 3,3',4,4'-benzophenone tetracarboxylic acid dianhydride (BTDA). These synthesized polyimides were dispersed in epoxy diamine networks to prepare composites. All the monomers and composites were characterized by making use of various analytical techniques including FTIR, NMR, TGA, DSC and XRD. Presence of hydroxyl group in the diamine helped in better dispersion of polyimide leading to high Tg and high char yield at 600 °C.
