Abstract:

A new conjugated aromatic poly[(furan-2, 5-diyl)-co-(benzylidene)] has been prepared by polycondensation of benzaldehyde and furan catalyzed by Maghnite-H+. Maghnite-H+ is a montmorillonite sheet silicate clay, which exchanged with protons. These polymers can be dissolved in high polar solvents such as DMSO, DMF, THF, or CHCl3 A kind of band-gap conjugated poly[(furan-2, 5-diyl)-co-(benzylidene)] has been synthesized by a simple method and characterized by 1HNMR, 13CNMR, FT-IR, and UV-Vis. The result reveals that the band-gap of the PFB conjugated polymer has an optical band gap of 2.2 eV.

Abstract:

Naphthoxazines are a class of compounds with potential application in obtaining high-performance polymeric materials. Such application of these compounds, however, is still scarcely explored in the literature. Combined with the search for new high-performance materials, the development of biobased polymers has gained a lot of attention. In this sense, the inclusion of furan groups in polymers has been explored as a strategy that combines the search for high-performance materials with the search for the development of biobased materials. In this work, novel naphthoxazine monomers containing fur

Abstract2,5-Furandicarboxylic acid is a platform chemical for the production of biobased polymers and materials. This study reports the synthesis of furan oligoesters via polytransesterification of dimethyl furan-2,5-dicarboxylate and linear α, ω-aliphatic diols with chain length ranging from C2 to C12, using immobilized lipase B from Candida antarctica (Novozym 435) in dry organic solvents. Dimethyl furan-2,5-dicarboxylic acid (A) and 1,4-butanediol (B) were used as model substrates under different conditions producing a mixture of cyclic (CEOs) and linear (LEOs) ester oligomers up to decamer

The article describes methods for producing polymeric materials based on tetra-carboxylic acid dianhydrides obtained by photochemical or solar irradiation from furan and maleic anhydride. The procedure of synthesis of aryl-alicyclic polyimides based on 7-оxsоdiciklo (2,2,1)-gepten -2,3- dicarboxylic acid(MAF) and diaminodiphenyl oxide diamines (DADFO) and dioxytriphenyldiamine (DOTFDA) in polar aprotic amide-type solvents has been studied in detail in the presence of a basic catalyst type: trimethyl-amine.The nature and reactivity of staring monomers affect the process of obtaining polyimides.

Abstract:

Abstract Polyimides (PIs) containing thermoplastic and thermosetting merged segments in a chain were developed via Diels-Alder (DA) polymerization of a bisfuran (BF), namely 2,5-bis(furan-2-ylmethylcarbamoyl)terephthalic acid and bismaleimides (BMI1 and BMI2). The intermediate DA polyadducts thus obtained, DAA1 and DAA2, were aromatized and imidized (cyclized) through carboxylic and amide groups in the presence of acetic anhydride, to afford PI1 and PI2. Synthesized DA polyadducts and PIs were characterized by elemental analysis, spectral features, number average molecular weight (Mn), degree

Abstract:

Dihydro-1,3,2H-benzoxazines (or benzoxazine monomers) are a class of compounds that have been widely utilized in many areas such as the production of the functional polymers and optoelectronic materials. The structure variety of the benzoxazines plays a vital role in their desired properties. The effort of synthesizing functionalized benzoxazines from bioresources is of interest for sustainable development. Herein, we report the synthesis of the novel benzoxazine monomer referred to as 3-(furan-2-ylmethyl)-6-methyl-3,4-dihydro-2H-benzo[e][1,3]oxazine or benzoxazine (I) from a one-pot Mannich r

Abstract:

Methyl oleate, methyl linoleate, and jatropha oil were fully epoxidized using in situ-generated performic acid. The epoxidized compounds were further reacted with furfurylamine in a solvent-free reaction to obtain furan-functionalized fatty esters which, then, functioned as oligomers for a network preparation. Thermoreversible crosslinking was obtained through a (retro) Diels–Alder reaction with bismaleimide, resulting in the formation of a brittle network for furan-functionalized methyl linoleate and jatropha oil. The furan-functionalized fatty esters were mixed with alternating (1,4)-polyket

A one pot-two step procedure for the synthesis of diethyl furan-2,5-dicarboxylate (DEFDC) starting from mucic acid without isolation of the intermediate furan dicarboxylic acid (FDCA) was studied.
