The research in this article explores the response of semicrystalline isotactic polypropylene to gamma radiation in air, and relates the morphological changes of the polymer to corresponding changes in mechanical properties. The effect of the initial morphology of the polymer on its response to irra
## Abstract Isotactic polypropylene (iPP) and iron oxide (Fe~3~O~4~) nanocomposites were mixed by masterbatch blending technique in a single screw extruder machine. The concentrations of Fe~3~O~4~ in the iPP/Fe~3~O~4~ nanocomposites were 0.5, 1, 2, and 5% by weight. The influence of Fe~3~O~4~ nanop
## Abstract A number of triazine derivatives, mostly aryloxyβ__s__βtriazines, were prepared, and the effects of these compounds on the thermal oxidative degradation of isotactic polypropylene were examined by conventional oxygen uptake. Almost all triazine derivatives prepared showed a more or less
