Research Abstract |
Since the chemiluminescence (CL) behavior in biodegradable polymers, which have carbonyl group in its structure, indicates a similar behavior of polyethylene (PE), it is thought that the carbonyl group consisted in the polymer structure exhibits no CL. While a silane coupling agent or a thiobis-based antioxidant, which is added in low density PE, exhibits no proper CL, a sulfur-based antioxidant, a halogen-based antioxidant, a metal hydroxide, an antirad, or an ion-trapping agent, which is added in ethylene propylene rubber (EPR), exhibits CL. The CL behavior in EPR is different to the one of LDPE or biodegradable polymers because of flame retarder added in EPR. Therefore, CL measurement is a good tool to evaluate the resistivity against oxidation of polymers.
