Abstract
The properties of blends of ethylene-co-vinyl acetate (EVA) and epoxidized natural rubber (ENR) have been studied in relation to their structures by Fourier Transform Infrared spectroscopy (FTIR) and dynamic mechanical analysis. FTIR spectra of the blends of EVA and ENR show weak dipole-dipole interactions. These blends are incompatible as determined from the dynamic mechanical analysis and further confirmed by scanning electron microscopy studies. In order to understand the influence of interaction between the polymers, the properties of blends of ENR with other reactive polymers such as ethylene-methylacrylate (EMA) and ethylene-acrylic acid copolymer (EAA), have been compared. The higher values of tensile strength and modulus of ENR/EAA are due to the higher level of interaction.
