| Abstract: | Polystyrene sulfonic acid was synthesized using sulfur trioxide and polystyrene in low temperature.The synthetic route was a green technology with fast reactive speed and fewer side products.The optimal reaction conditions were as follows：-20℃ under atmospheric pressure when the chloroform as solvent,sulfur trioxide and polystyrene by the mass ratio of 0.8∶1,low-speed stirring of 30min,aged of 30min.The sulfonation degree of the synthesized product is 92.45% after purification,and it could be controlled by the variations of mass ratio of sulfur trioxide. |
