Thermally stable materials can be achieved by crosslinking. This article presents the thermal aging and thermal energy storage properties of ethylene-octene copolymer (EOR) and low-density polyethylene (LDPE) blends as affected by silane crosslinking. Fourier transform infrared spectroscopy revealed a similar degree of silane grafting among the various blend compositions. However; the highest crosslink content was observed in EOR; whereas the lowest was found for LDPE. From melting temperature and heat of fusion data; a linear relationship between the amount of the crystalline component and the crosslink content was found. The decrease in crystallinity due to crosslinking was very limited; which implied a high thermal energy storage capacity of the silane-crosslinked products and their good mechanical properties at room temperature. Furthermore; a strong ability to retain the properties after thermal aging indicated good thermal stability of the materials. © 2008 Wiley Periodicals; Inc;
