abstract |
The present invention relates to a novel sulfobetaine monomer, and its preparation process, advantageously by reaction between a vinyl-amine compound and a vinyl-sulfonic acid compound, preferably in the presence of a solubilizing agent. The present invention also relates to the (co) polymers obtained from this new type of sulfobetaine monomer, and their use, for example as a flocculant, dispersant, thickening agent, absorbing agent or friction reducing agent. |
