• Extending Primary Ammonium Dicarboxylate (PAD) to Diprimary Ammonium Dicarboxylate (DPAD) Synthon and Its Implication in Supramolecular Gelation

  A series of organic salts derived from various dicarboxylic acids and two alpha,omega-diamines, namely, 1,3;diaminopropane and 1,4-diaminobutane, were prepared and characterized by various physicochemical techniques, including single-crystal X-ray diffraction, with the aim of extending the well-studied 2D primary ammonium dicarboxylate (PAD) supramolecular synthon in the context of supramolecular gelation. Single crystal structures of 9 out of 14 diprimary ammonium dicarboxylate (DPAD) salts were determined. The results showed that none of the salts displayed the expected 2D DPAD synthon; instead, all of them self assembled into a 3D hydrogen bonded network. Consequently, only two salts, namely, B(3)FA and B(4)SA, appeared to show gelation behavior producing weak gels-a finding that corroborated well with the current understanding of gelation.

  The invention relates to a thermoplastic composition comprising (A) a semi-aromatic copolyamide comprising repeat units derived from diamine consisting primarily of tetramethylene diamine and hexamethylene diamine, or pentamethylene diamine and hexamethylene diamine, and dicarboxylic acid consisting primarily of terephthalic acid, having a VN of at least 100 ml/g; and (B) a reinforcing agent. The invention also relates to a plastic part made of the thermoplastic composition. The invention further relates to an automotive vehicle comprising a structural part made of the thermoplastic composition and to an electrical assembly comprising a plastic component made of the thermoplastic composition.
