Polymethyl methacrylate/50% epoxidized natural rubber (PE) blend and polymethyl methacrylate/50% epoxidized natural rubber/silicon dioxide (PE15) nanocomposites were successfully prepared via solvent casting method with tetrahydrofuran (THF) as solvent. The interactions between silicon dioxide (SiO2) particles with polymethyl methacrylate (PMMA) and 50% epoxidized natural rubber (ENR 50) in PE and PE15 films were investigated using Fourier transform infrared (FTIR) analysis. Meanwhile, the phase separation between PMMA and ENR 50 in PE and PE15 films was monitored using optical microscopy (OM) analysis. FTIR analysis shows the presence of hydrogen bonding between PMMA and ENR 50 in PE film and functional groups responsible to the hydrogen bonding was identified. FTIR analysis also revealed that interactions between SiO2 with PMMA and ENR 50 were SiO2 weight percent dependent. While, OM analysis confirmed that phase separation between PMMA and ENR 50 also influenced by weight percent of SiO2. © 2018, Malaysian Society of Analytical Sciences. All rights reserved.
