In this paper, thermogravimetric analysis of different types/grades polyvinyl chloride (PVC) wall panel is carried out using analyzer. The data output from the analyzer subjected to software i.e., OriginPro 2018, which thermal attributes are find for grades PVC soft PVC, hard WPVC and SPVC. onset degradation temperature T i , final f ,, reaction interval peak P derivative curve four basic types...

1, 4-Diazabicyclo [2.2.2] octane (DABCO) was employed as a catalyst for one-pot synthesis of pyrano[2,3-d] pyrimidinone derivatives and MWNT- pyrimidinones from condensation reactions of aromatic aldehydes, malononitrile and thiobarbituric acid and MWNT-COCl . This method delivers the advantages of a simple method, environment friendly procedure, mild reaction conditions and high returns. The m...
