Description

The static and dynamic compressive properties of polypropylene/Degra-novon polymer blends after outdoor (natural) weathering and accelerated weathering tests were measured using a universal testing machine and a split Hopkinson pressure bar. Degra-novon in polyolefins, such as polypropylene and polyethylene, accelerates the environmental degradation process by providing a directly digestible component, facilitating oxidation and/or photodegradation of the polymer chains. The relationship between the mechanical properties, differential scanning calorimetry results, and Fourier transform-infrared spectroscopy data were also examined.
