The thermal stabilization of poly(vinyl chloride) through blending techniques has been studied. Poly(vinyl chloride) was blended with modified polymer (cellulose acetate-diallyl amine) in different compositions to improve the thermal stability of poly(vinyl chloride). The thermal stability and morphology of the blend films were characterized by scanning electron microscope (SEM) and thermogravimetry. The results revealed that the presence of modified cellulose acetate improved the thermal stability of poly(vinyl chloride). This was attributed to the thermal stable diallylamine moieties among the cellulose acetate chains. The addition of traces of maleimide derivatives to poly(vinyl chloride) prior to the blend process led to an extra thermal stability of the blend film as shown from the values of the initial decomposition temperature (To) measured by thermogravimetry.

Nickel(II) tetraphenylporphyrin (NiTPP) is presented as a robust, cost-effective and efficient visible light induced photoredox catalyst. The ground state electrochemical data (CV) and electronic absorption (UV-Vis) spectra reveal the excited state redox potentials for [NiTPP]*/[NiTPP].? and NiTPP].+/[NiTPP]* couples as +1.17 V and ?1.57 V vs SCE respectively. The potential values represent NiTPP as a more potent photocatalyst compare to the well-explored [Ru(bpy)3]2+. The non-precious photocatalyst exhibits excited state redox reactions in dual fashions, i. e., it is capable of undergoing both oxidative as well as reductive quenching pathways. Such versatility of a photocatalyst based on first-row transition metals is very scarce. This unique phenomenon allows one to perform diverse types of redox reactions by employing a single catalyst. Two different sets of chemical reactions have been performed to represent the synthetic utility. The catalyst showed superior efficiency in both carbon-carbon and carbon-heteroatom bond-forming reactions. Thus, we believe that NiTPP is a valuable addition to the photocatalyst library and this study will lead to more practical synthetic applications of earth-abundant-metal-based photoredox catalysts.
