| 摘 要： | Acetyl crosslinked polystyrene (EPS) and crosslinked bromoacetyl polystyrene (BEPS)beads were synthesized by Fridel-Crafts acetylation of polystyrene (PS) and bromination of EPS respectively. FTIR, XPS, and TG-TDG were employed to characterize their structures. The results revealed there are two types of bromine in the BEPS molecule. One is in the main chain of polystyrene and the other is in the acetyl. The results of TG-DTG showed that the rates of loss weight of PS, EPS, and BEPS were 92.7%, 92.2%, and 81.3% among the 300 ℃～500 ℃; 7.3%, 7.8%, and 18. 7% in 594 ℃, 660 ℃, and 584.8 ℃, respectively. |
