ABSTRACT = {The weathering performance of polypropylene (PP) was studied in an artificial accelerated
weathering chamber of 340 nm ultraviolet light and natural conditions in Turpan, China. This
work aimed to provide a method for calculating the aging failure of PP under natural conditions
by the means of artificial accelerated aging. SEM showed that large crack widths of approximately
1.25 µm and 1.63 µm appealed on the PP surface after 15 days artificial accelerated aging and
150 days natural aging, respectively. XPS data revealed that the number of C-O and C=O
bonds on the PP surface were generally the same after artificial accelerated aging and natural
aging of PP for 3 and 30 days, 6 and 60 days, or 9 and 90 days, respectively. Moreover, the data
of mechanical properties and capillary rheology also exhibited similar results. It was concluded
that the aging rate of artificial accelerated aging was 10 times faster than that of natural aging
in Turpan.},
