Studies on Thermal and Morphological Behavior of 3- Aminopropyltriethoxysilane Grafted Epoxidized EthylenePropylene-Diene Terpolymer

Abstract

A novel and new copolymer of 3-aminopropyltriethoxysilane (APTES) on epoxided ethylene-propylene-diene terpolymer (eEPDM) via Sol-Gel Process. EPDM was epoxidized with an in situ formed per formic acid to prepare epoxided EPDM (eEPDM).The effect of eEPDM concentration, APTES concentration, reaction time and reaction temperature on the graft co polymerization was studied. The grafting efficiency of APTES on eEPDM, eEPDM was confirmed by Fourier Transform infrared (FT-IR) spectroscopy. The Thermal behaviors of EPDM, eEPDM, g-EPDM were studied by Thermo gravimetric analysis and DSC. The Morphological properties of Epoxidation of EPDM and eEPDM-g-APTES are compared.
