Definitions
- the polymer is dispersed or dissolved in a solvent resistant to SO -cg. a perhalogenated solvent-and then treated with S0, gas to cause sulfonation to take place.
- a solvent resistant to SO -cg. a perhalogenated solvent-and then treated with S0, gas to cause sulfonation to take place.
- S0 sulfur dioxide
- gas gas to cause sulfonation to take place.
- sulfonation is rather slow, and refrigeration expensive; while reaction is feasible, we prefer to operate above this temperature. Above about 20 C., some discoloration of the product occurs, so that we prefer to keep temperatures down to this figure.
- the reaction can be carried out outside of this range of about 0-20 C., with only the indicated disadvantages.
