    Two series of novel, partially bio-based aromatic polyimides (PIs) derived from two new 2,5-furandicarboxylic acid-based diamines are synthesized. These PIs possess excellent properties such as high glass transition temperatures, good transparency and outstanding mechanical properties, which are comparable with the petroleum-based PIs derived from isophthalic acid. They display potential as alternatives to petroleum-based high performance resins. This work contributes to the rapid development of renewable and bio-based polymers.

    A novel type of triple redox/temperature-responsive diselenide-containing poly(methoxydiethylene glycol-l-glutamate) homopolypeptide was facilely synthesized, which exhibited triple stimuli-sensitive self-assembly behaviors. The diselenide-containing homopolypeptides formed supramolecular hydrogels and the mechanical modulus can be tuned by changing the chain length of the homopolypeptide, the 10-mM 1,4-dithiothreitol reduction, and 1 mM H2O2 oxidation, respectively. Consequently, this work provides a simple strategy to fabricate triple-stimuli responsive polypeptide micelles and one-component hydrogels.

  4. A novel synthetic strategy for preparing semi-aromatic components modified polyamide 6 polymer

    Purified terephthalic acid and hexamethylene diamine were dissolved in the main reactant caprolactam according to the stoichiometric ratio. Through ring-opening, poly-addition, and poly-condensation reactions at high temperature, polyamide-6 is modified with transparent semi-aromatic components, endowing it with a higher decomposition temperature and good mechanical properties. Using this time-reducing green synthetic path, the yield of caprolactam was also significantly increased compared with the conversional hydrolytic polymerization process.

  5. Soluble polybenzimidazoles with intrinsic porosity: Synthesis, structure, properties and processability

    Soluble porous polybenzimidazoles (PBIs) based on rigid and contorted monomers, namely, 4,16-dicarboxyl[2.2]paracyclophane and 5,5′,6,6′-tetraamino-3,3,3′,3′-tetramethyl-1,1′-spirobi [indane] were synthesized. Comonomer (10 mol %) insertion resulted in soluble PBIs. Amorphous PBIs exhibited high glass transition temperatures and thermal stability. HR-TEM and BET provide evidence of porosity. The basic nature of imidazole promoted carbon dioxide absorption. Molecular dynamic simulations indicate that cyclophane and spirobisindane monomers result in structures with large intramolecular voids. This method provides a “bottoms-up” approach for the synthesis of soluble mesoporous PBIs.
