摘要：The effects of time and temperature level on the aging of the 791-H SBS modifier have been investigated through experimental study. A series of Thin Film Oven (TFO) Test was conducted at the temperature of 100°C and 163°C and time of 1, 2, 5 and 10h. The changes in the chemical composition due to oxidative aging are detected by Fourier Transform Infrared Spectroscopy (FTIR) test. The results show that the visual observation of SBS after aging within 10h is almost unchanged when the aging temperature is 100°C. At 163°C within 1-2h aging, the SBS particles gradually softened and become slightly bonded to each other; at the same temperature after 5h of aging, the particles of SBS became yellow. The result from FTIR test shows that temperature is an important factor in the aging of SBS modifier and its effect on the aging of SBS modifier is much greater than that of aging time.
