The thermal properties of coordination compounds of the composition Cu(NCS)2L2 (whereL=pyridine, 2-, 3- and 4-picoline, and 2,3-, 2,4-, 2,5-, 2,6-, 3,4- and 3,5-lutidine) are dealt with. The thermal decomposition of these compounds begins with the release of the ligandL. The compounds with pyridine derivatives containing a methyl substituent at position 2 show a markedly decreased initial decomposition temperature. It was found that X-ray irradiation caused a reduction of the central atom Cu(II) in the coordination compounds under investigation. X-ray electron spectra data showed the stability of the compounds Cu(NCS)2L2 withL=picoline or lutidine having a methyl substituent at position 2 to be distinctly lower in the surface layers. From the given series, the compounds Cu(NCS)2(pyridine)2 and Cu(NCS)2(3,5-lutidine)2 exhibit an analogous course of thermal decomposition in nitrogen atmosphere up to 600°. The stoichiometries of thermal decomposition are discussed.

We describe an application of DSC as an analytical ‘fingerprinting’ method that has been used to characterize the thermal properties of wheat starch in low-moisture, wheat-flour-based baked products, including cookies, crackers, and pretzels. This use of DSC has enabled us to relate starch thermal properties, on the one hand, to starch structure, and on the other hand, to starch functionality, in terms of baking performance and finished-product quality.
, characterization and thermalproperties of highly crosslinked, hydrophilic stable spherical microspheres based on the new aromatic tetrafunctional methacrylate monomers and divinylbenzene (DVB) prepared by emulsion–suspension polymerization in the presence of pore
The effects of low-density polyethylene or isotactic polypropylene on the thermal properties of ethylene-propylene-diene rubber were examined by using a rheometer and a derivatograph. Pronounced changes in the thermal properties of the rubber were observed as a result of the polyolefin addition.
The effect of mixed synthetic saturated acids and of cobalt salt of these acids on the thermal properties of peroxide vulcanizates ofcis-1,4-polybutadiene, Europrene cis, has been studied by derivatography.
