Process for the impregnation of fibers of a tobacco smoke filter with dicarboxylic or polycarboxylic acids or anhydrides thereof |
| abstract |
Fibers of tobacco smoke filters which have been impregnated with dicarboxylic or polycarboxylic acids or anhydrides thereof can be obtained by dissolving anhydrides of dicarboxylic or polycarboxylic acids in volatile or physiologically acceptable organic solvents and applying them to the fibers and, if appropriate, hydrolyzing them with water. |
