A series of copolymers based on s-triazine and ethylene diamine moiety were synthesized; the prepared copolymers were characterized by FT-IR, TGA, DSC, and GPC. The thermogravimetric anal. of and the thermal stability of the copolymers were used to investigate their non-isothermal behavior. The comparative kinetic study was done using Kissinger method as a model-free; in addition, iso-conversional methods of Kissinger-Akahira-Sunose (KAS), Flynn-Wall-Ozawa (FWO) and Friedman (FR) are reported. The activation energy data extracted by the KAS, FWO and FR fit well with each other (as they are showing the same trend). Generally, the activation parameters were highly dependent on the copolymer’s mol. structure. In addition, the substituent on the triazine core has a great impact, where the activation parameters increased in the presence of an electron-donating group such as a methoxy group (OCH3) on the aniline moiety. In contrast, it has decreased in the presence of the unsubstituted and p-bromo derivative (week deactivating group). On the other hand, the methoxy group attached to the aniline moiety gave the highest ash formation and the highest limiting oxygen index (LOI) value (29.45). This study involved multiple reactions and reactants, such as 4,6-Dichloro-N-phenyl-1,3,5-triazin-2-amine (cas: 2272-40-4SDS of cas: 2272-40-4).
4,6-Dichloro-N-phenyl-1,3,5-triazin-2-amine (cas: 2272-40-4) belongs to organic chlorides. Chlorination modifies the physical properties of hydrocarbons in several ways. These compounds are typically denser than water due to the higher atomic weight of chlorine versus hydrogen. Alkanes and aryl alkanes may be chlorinated under free radical conditions, with UV light. However, the extent of chlorination is difficult to control.SDS of cas: 2272-40-4
