Özet
In this study, five new organometallic barbiturate complexes which are described in Cu(C4H3-N2O3)(2)center dot 2H(2)O (1), Cd(C4H3N2O3)(2)center dot 4H(2)O (2), Sn(C4H3N2O3)(4)center dot 4H(2)O (3), Sn(C4H3N2O3)(2)center dot Ni(B4O7)center dot 4H(2)O (4), Sn(C4H3N2O3)(2)center dot Cu(B4O7)center dot 3H(2)O (5) have been synthesized. Their contribution to the thermal and UV stabilization of PVC was investigated by thermostatic analysis via according to ISO 182-2 standard. Additionally, the structural properties of the synthesized complexes were investigated by elemental analysis, powder XRD and vibrational (FT-IR and Raman) spectroscopic techniques. Furthermore, complex 1 has been investigated by single crystal X-ray diffraction technique. The results are shown that synthesized complexes act as HCl scavengers during the PVC decomposition. The thermal decay of PVC dough, which is including in new generation plastic additives, are following: 1 > 3> 5 > 2>4. (C) 2019 Elsevier B.V. All rights reserved.
