Synthesis and characterization of some new Schiff base ligands derived from various diamines and nitrosalicylaldehyde and their complexes of Ni(II) and Cu(II) are reported. Several spectral techniques such as UV-Vis, FT-IR, and NMR spectra were used to identify the chemical structures of the reported ligands and their complexes. The ligands are found to be bound to the metal atom through the oxygen atoms of the hydroxyl groups and nitrogen atoms of imine groups, which is also supported by spectroscopic techniques. The results obtained by FT-IR and NMR showed that the Schiff base complexes of transition metal (II) have square-planar geometry.

AbstractThis work focuses on using analytical methods, such as Fourier transform Infrared spectroscopy (FTIR) and high performance liquid chromatography (HPLC) with mass spectrometry (MS) detection to assess archaeological and geological amber. The main goal of this study is to apply the previously developed and optimized analytical methods in verifying criteria to ascribe and characterize the origin of materials found in archaeological sites. The proposed LC-MS method was successfully applied for the quantification of succinic acid content both in geological and archaeological samples of amber and offers excellent linearity between 0.1 and 5µg mL−1. The developed FTIR method provided some criteria which is able to differentiate between Baltic and Romanian amber (Romanite) that furthermore validates on archaeological amber artefacts.

Abstract. Polyaniline (PANI) and p-phenylenediamine (p-PDA)-aniline copolymer were prepared via a same microemulsion method. The structures of the PANI and p-PDA-aniline copolymer were characterized by infrared spectroscopy (FT-IR), X-ray diffraction (XRD), thermogravimetric analysis（TGA）. The results revealed the difference of synthesis and characterization between PANI and p-PDA-aniline copolymer. It was shown that structure of the copolymer is almost similar to that of PANI, but the p-PDA-aniline copolymer has a better crystallization than PANI, and the thermal stability of the copolymer is higher than that of pure PANI.

<p>The aim of this research was the synthesis of polymers with the addition of S,S'-thiodi-4,1-phenylene bis(thiomethacrylate) (DMSPS) by bulk polymerization. Styrene (St), divinylbenzene (DVB) and ethylene glycol dimethacrylate (EGDMA) were used for the copolymerization as main monomers. The chemical structures of sulfur-containing polymers were confirmed by the spectroscopic analysis (ATR/FT-IR). In order to determine the impact of the sulfur derivative (DMSPS) addition on thermal properties of the obtained copolymers, differential scanning calorimetry (DSC) was performed. The hardness tests of the obtained copolymers were also applied using a Shore durometer.</p>

By the coupling of thermogravimetry (TG) and Fourier transform infrared spectroscopy (FT-IR), the thermal behavior of polymeric materials can be elucidated from their mass loss combined with characterization of the evolved components. A hyphenated TG/FT-IR technique is presented, which enables the direct detection and characterization of evolving components in TG experiments, i.e., without transferring these components from the TG to the FT-IR equipment. In this on-the-spot TG/FT-IR technique, the IR beam of the FT-IR spectrometer is led directly into the TG equipment. The IR beam is reflected by a mirror mounted inside the TG equipment and subsequently detected by a standard FT-IR detector. In this way, the evolved components are detected both in gas and condensed phase directly in the TG equipment. The detection limits are in the sub µg/s range. The experimental setup and conditions are presented together with advantages and applications in the field of polymeric research.

In this study, a novel flame retardant 1,2-bis (dimelaminium of 1-nitro-3,5-diphospha-4-oxa-3,5-dihydroxy cyclohexane) ethane (EAPM) was synthesized by ethylene diamine tetra (methylene phosphonic) acid (EDTMPA) and melamine in two steps. Meanwhile, its molecular structure was determined by Fourier-transform infrared spectroscopy (FT-IR), elemental analysis, 1H-NMR. The thermal properties were characterized by TG and DTG, which indicated the good thermostability of EAPM for processing and the considerable residual char in the final stage of combustion. The fire performance of composites blended by the novel flame retardant and polypropylene waere investigated by limiting oxygen index (LOI) and vertical burning test. The results demonstrated the treated PP with the optimal flame retardant formulation of 15 w% EAPM, 5 w% charring agent and 10 w% MEL-APP was attached with an LOI of 33.3% and UL-94 V-0 rating.
