High surface area adsorbents and method of preparation |
摘要 |
A process for the preparation of high surface area, low-swelling macroporous polymeric adsorbents is disclosed. The use of organic sulfonic acids to provide postcrosslinking of macroporous copolymers eliminates the need for traditional organic swelling solvents and Lewis-acid catalysts used to provide conventional macronetted polymers. In particular, methanesulfonic acid provides macroporous polymeric adsorbents having high surface area and porosity, low levels of residual vinyl groups, and free of residual contaminants from conventional Lewis-acid/Friedel-Crafts reactions. |
