Bio-based diamines are considered to be a promising alternative to traditional fossil-fuel-based diamines,the important platform chemical for the synthesis of polymer materials.In this review,the current status of the art of the synthesis of aliphatic and aromatic diamines from renewable biomass are considered.In the case of aliphatic diamines,we describe strategies for biologically producing diamines with different carbon numbers including 1,3-diaminopropane,1,4-butanediamine,1,5-pentanediamine,1,6-diaminohexane,1,8-diaminooctane,1,10-diaminodecane,and 1,12-diaminododecane.In addition,aromatic diamines produced from various kinds of renewable biomass,including lignin,cashew nut shell,and terpenoids,are reviewed here.Furthermore,the application of typical diamines in synthesis of polyurethane and polyamide are also reviewed.

Di(4-bromophenyl)ketone and various aromatic diamines as the monomers,a series of novel poly(imino ketone)s (PIKs)have been synthesized via palladium-catalyzed aryl amination,which is Hartwig-Buchwald polycondensation reaction.The structures of PIKs are characterized by means of elemental analysis,FT-IR,~1H-NMR and UV-Vis spectroscopy. The results show a good agreement with the proposed structure.The general properties of PIKs are studied by DSC,TG and wide-angle X-ray diffraction,the solubility behavior is...

Synthesis and Characterization of Polyamides Based on Dimer Acid

引用

Journal of Wuhan University of Technology(Materials Science) 2009年第3期24卷 367-370页

作者：王文志章永化 College of Materials Science and Engineering South China University of Technology

A series of dimer acid-based polyamides were synthesized by melt-polycondensation of dimer acid and various aromatic diamines, and were characterized by Fourier transform infrared spectrum （FT-IR） and nuclear magnetic resonance （^1H NMR）. The physical properties of the polyamides, such as glass transition temperature, melting temperature, decomposition temperature and mechanical properties were also investigated. The polyamides＇ intrinsic viscosity ranges from 1.8 dL·g^-1 to 2.2 dL·g^-1, and the melting temperature ranges from 140 ℃ to 181 ℃. The glass transition temperatures, observed from dynamic mechanical analysis, fall in the range of 34.8-48.2 ℃. The physical and mechanical properties of the resultant polyamides are similar to those of the PA1212. The heat resistance and mechanical properties of poly （4, 4′-diphenylsulfone dimeramide）（PSD） and poly（4, 4′-di pb enyl dimeramide）（PPDI） are comparable to those of PA 1212.

Thermo-oxidative Oligomerization of aromatic Diamine

引用

Organic Polymer Material Research 2021年第1期3卷 24-31页

作者： B.А.Zaitsev L.G.Kleptsova I.D.Shvabskaya А.E.Bursian Institute of Macromolecular Compounds Russian Academy of SciencesSaint Petersburg199004Russia

Molecular spectroscopy(electronic,FT-IR,NMR),methods of thermal and elemental analysis were used for the first time to describe the process of thermo-oxidative oligomerization of 1,3-bis-(4-aminophenoxy)benzene.Introduction of this monomer into linear and network copolymers makes it possible to improve processability,mechanical strength and heat resistance of materials.The structures of copolymers obtained by thermo-oxidation of the diamine in various thermal regimes were studied.It was demonstrated that during prolonged heating of this diamine in air in the temperature range from 220 to 320°C,oligomeric aromatic diamines were formed;these products contained fragments of benzenoid and quinoid types.
