ABSTRACT
Microwave-assisted selective degradation successfully converts thermosetting unsaturated polyester resins into a low-swelling (below 10â¯g g-1) gel material (GM) with a high yield (58-65%) in water at 100°C for only 1â¯h. The obtained GM possesses rough and porous structure while the content of carboxylate group obtained by cleavage of partial ester groups is more than 10%, varying with the concentration of the catalyst. It is suitable for use as packing of adsorption column to rapidly purify sewage. Super high filtering rates of 18582-27002â¯Lâ¯h-1â¯m-3 without external pressure and high removal efficiency of more than 99.8% were achieved, promoting practical application for rapid removal of organic pollutants.
