Summary: Polyamic acid (PAA) was synthesized using specific monomers and transformed into colorless transparent poly(amide imide) (CPAI) hybrid films. The CPAI hybrid films were prepared by dispersing organoclay STN in CPAI, and the properties were studied based on the dispersed STN content. While some clay were agglomerated, most clays were well-dispersed in nano-size. The best thermomechanical properties were achieved with an STN content of 3 wt%.

Summary: Nonstoichiometric polyaddition was achieved through Co-catalyzed hydroarylation of diyne monomers with excess 1-(2-pyrimidinyl)pyrrole. The 2-pyrimidinyl substituent acted as a directing group, facilitating intramolecular catalyst transfer and yielding poly(arylenevinylene)s with alkyne terminals and high molecular weight.

Summary: In this study, ternary superparamagnetic nanocomposites consisting of graphene oxide (GO), Fe3O4 nanoparticles, and optically active poly(amide-imide) (PAI) were successfully fabricated. The nanocomposites exhibited excellent properties after a facile one-pot synthesis of Fe3O4 on GO, modification of Fe3O4@GO, and subsequent composite formation with chiral PAI.

Summary: High-performance engineering thermoplastics show excellent thermomechanical performance and chemical resistance, but the rigid polymeric main chains derived from highly or fully aromatic repeating units pose processing challenges. A novel design of photo-reactive precursors has enabled additive manufacturing of poly(amide imide) (PAI) precursor organo-gels via UV-assisted direct ink write (DIW) printing, with high solution viscosities and shear thinning behavior being key requirements for successful production. The resulting self-supporting organo-gels exhibit rapid gelation and high gel strengths, allowing for further thermal post-treatment with isotropic linear shrinkage and the formation of desired multiphase polymers.

Summary: A series of high molecular weight poly(amide-imide)s containing cardo structures were successfully synthesized via a supported palladium-catalyzed carbonylation polymerization. These polymers exhibited high thermal stability, excellent mechanical properties, and high optical transparency. The supported palladium catalyst used in the process could be conveniently separated and recycled multiple times without significant loss of catalytic efficiency.

Summary: This study established a highly efficient catalyst-free synthetic method for optically active polysulfonamide derivatives with controlled linear architecture using chiral bis(2-substituted N-sulfonyl aziridines) as catalysts. Novel poly(sulfonamide amine)s were synthesized through step-growth polymerization, achieving good yields. A one-pot, two-step protocol was developed for the synthesis of poly(sulfonamide dithiocarbamate)s using in situ generated bis(dialkyldithiocarbamate) as the nucleophile. This approach avoided the branches or cross-linkages derived from the homo-polymerization of aziridines.

Summary: Two series of poly(amide imide)s (PAIs) were synthesized via thermal imidization using novel isomeric amide-containing diamine monomers and different commercial aromatic dianhydrides. These PAIs exhibited excellent thermal and mechanical properties, making them potential candidates for flexible displays. The effects of the isomeric monomers on film properties were compared.
