Thermal stability of solution-cast blends of poly(vinylchloride) and NR-b-PU block copolymers of three different chain extender diols was studied by thermogravimetry. Thermal degradation of individual components and their blends were investigated with special reference to blend ratio. As the block copolymer content in the blends increased their thermal stability was also found to increase. Enhanced thermal stability of PVC is believed due to the favorable interaction with PVC and the PU hard segments of the block copolymer. DTG curves were used for the determination of different stages involved in the degradation. Activation energy for degradation was determined from Coats–Redfern plot.

The existence of an inner sphere water in sodium tris-carbonatocobaltate(III) prepared by the Bauer and Drinkard method was
confirmed by thermogravimetry, which led to its formulation as sodium aquo-tris-carbonatocobaltate(III) dihydrate, Na3[Co(H2O)(CO3)3]·2H2O. Hydrolytic study on 4-nitrophenylphosphate promoted by [Co(tn)3]3+ afforded corborating evidence for the existence of inner sphere water in the complex leading to its formulation as [Co(tn)3(H2O)]3+. Another variety of the tris-carbonato anion, [Co(NH3)6][Co(CO3)3], was prepared and subjected to thermogravimetric analysis, and the absence of inner sphere water in the compound was confirmed.
The plausible existence of inner sphere water for the compounds that emanate from the synthetic routes utilizing the Bauer
and Drinkard method in the crystalline phase is proposed.
