SULFONYL-CONTAINING POLYMERS BASED ON FREE-RADICALLY POLYMERIZABLE SPIROBISINDANE MONOMERS

摘要

Sulfonyl-containing polymeric materials and methods of making these materials are provided. More specifically, the sulfonyl-containing polymeric materials are prepared by treating a precursor polymeric material with a sulfonyl-containing compound. The precursor polymeric material is formed from a polymerizable composition that contains a free-radically polymerizable spirobisindane monomer. The sulfonyl-containing polymeric material is porous. The size of the pores can be in the microporous region, mesoporous region, or both depending on the particular monomers and reaction conditions used to form the precursor polymeric material.
