Abstract：The hot oxygen aging of SIS in home-made hot oxygen aging set was studied.Accordingto the anti aging characteristic of various antioxi-dants, a sort of antioxidant composites was pre-pared. The result of experiment showed that the antiaging effect of the composites was good, and usingthis antioxidant could solve the aging of SIS in thehot melt pressure sensitive adhesive.
