Summary
Low density Polyethylene (LDPE) and Ethylene Vinyl Acetate (EVA) Copolymer have been processed at 170°C for 7 minutes. Dynamic mechanical analysis shows a single composition dependent glass transition temperature of the 50:50 EVA/LDPE blend. Infrared spectra of pure EVA processed at the same condition shows splitting of >C=0 stretching band of EVA while spectra of the 50:50 EVA/LDPE blend shows a well resolved single band. Thermogravimetric analysis of the blend shows greater stability than those of the pure components. A schematic mechanism ascribing to the synergistic effect observed is proposed.
