FLUORINE POLYMER SOLUTIONS |
| abstract |
In mixtures of aprotic solvents, such as dimethylformamide and anhydrous carboxylic acids, fluorine-containing polymers containing -COOH groups dissolve without degradation if these groups are first converted into -COON(R)4 groups by reaction with tetraalkylammonium compounds. Such solutions can be used to produce cast films which, after reconversion into the -COOH form, are used as cation exchanger membranes. Films or coatings made from such solutions can also be used on greenhouse covers, where their hydrophilic surface allows condensation to run off more easily. Other applications relate to ion exchangers on supports and catalysts for chemical reactions. |
