The influence of increase in both environmental temperature due to global warming and ozone concentration caused by ultraviolet on polymers has been worried. PP homopolymer without antioxidant was subjected to accelerated weathering test. Degradation rate of PP was synergistically increased by combination of degradation factor, i.e. light, heat, and water. The degradation rate reached 6 times or more, based on carbonyl index.
