A series of new mixed ligand complexes of cobalt(II), nickel(II), copper(II) and cadmium(II) have been synthesized with 3-benzyl-1H-4-[(2methoxybenzylidine) amino]-1, 2, 4-triazole-5thione (MBT), 3-bezyl-1H-4-[(4-chlorobenzylidine) amino]-1, 2, 4-triazole-5-thione (CBT), 3-benzyl1H-4-[(4-nitrobenzylidine)amino]-1, 2, 4-triazole5-thione (NBT) and dehydroacetic acid sodium salt (Nadha). The mixed...

Mononuclear and polynuclear chelates of potassium picolinoyldithiocarbazate (KHPcDC) with Mn(II), Fe(ll1), Fe(II), Co(Il), Ni(II), Cu(II), Zn(II), Cd(II), Hg(II), Pd(II) and U(VI)O2 have been prepared and characterized by chemical and thermal (TG, DTG, DTA) analyses, molar conductivities, spectral (UV-Visible, IR, NMR, ESR) and magnetic moment measurements. The molar conductivities of the compl...

A complex of Cu(II) with 1-(6-HydroxyNaphthalen-2-yl) Butane-1,3-Dione (HNBD) was synthesized and characterized by elemental analysis, IR, UV and DTA-TG-DTG techniques.    IR spectra as well as UV-visible absorption measurements indicated that Cu(II) ion was coordinated to the HNBD ligand. The TG-DTA-DTG curves showed that thermal decomposition o...

Abstract Ceramic polymer materials have great future applications in the field of fireproof materials. However, ceramic polyolefins shortcomings such as few available inorganic fillers, high sintering temperature, and low flexural strength. Therefore, achieving rapid ethylene‐propylene‐diene rubber (EPDM) is an urgent problem that needs to be solved. Herein, we prepared EPDM using pyrophyllite ...

The behaviour of poly(methyl methacrylate) was examined in the presence of phosphorus tribromide (PBr3) with varying concentrations. Films were cast from common solvent and subjected to TG, DTA, DTG, IR and Py-GC-MS for evaluating the degradation routes. Despite early decomposition of the blends, certain temperature zones were identified for stabilization of the system. New products were found ...
