Özet:

 The three derivatives polyPOHMAC-co-VTM-g-Fe3O4, polyPOHMAC-co-VTM-g-Fe3O4 and PVC-g-polyPOHMAC-co-VTM-g-Fe3O4 were characterized based on thermal properties. The thermal properties like initial decomposition and final decomposition temperatures and temperature at the maximum rate of decomposition were studied by thermogravimetry TG and differential thermal gravimetry DTG and the decomposition steps were investigated. Then, the thermal characteristics of the final product formed via click chemistry, PVC-g-polyPOHMAC-co-VTM-g-Fe3O4 were evaluated through thermogravimetry analysis TGA under argon atmosphere at 5, 10, and 15 oCmin. The temperature range studied is 0 to 800oC. Based on the iso-conversional method, the thermal degradation kinetic parameter of the activation energy was calculated by the free model methods of the Flynn-Wall-Ozawa method FWO and Kissinger-Akahira-Sinuse method KAS. The predicted activation energy values ranged from 41.40 to 117.83 KJmol-1 meanwhile the average activation energy values were calculated as 85.75 KJmol-1 and 72.31 KJmol-1 respectively for FWO and KAS methods. In addition, the saturation magnetization value of 33.7 emug was recorded using the vibration sample magnetometry VSM.
