Abstract: A composition for capture of acid gas comprising solid porous particles of hypercrosslinked polymer comprising a network of aryl groups linked by methylene (—CH2—) bridging groups formed by Friedel-Crafts catalyzed polymerization or Friedel-Crafts catalyzed post-polymerization cross-linking; wherein the solid porous particles of hypercrosslinked polymer contain absorbed liquid comprising an acid gas absorbent selected from chemical absorbent for acid gas, physical absorbent for acid gas or mixture thereof and the weight ratio of absorbed liquid to solid porous particles of hypercrosslinked polymer is from 1:1 to 5:1.
