| titleOfInvention | Novel comb copolymer and process for the preparation thereof |
| abstract | A comb polymer of which the backbone is 2-acrylamido-2-methylpropanesulfonic acid, onto which poly(N-alkylacrylamide) or poly(N,N-dialkylacrylamide) lateral segments are grafted; process for the preparation thereof comprising: -a step (a) of reacting a compound of formula (II) with a compound of formula (III), in a (tert-butanol)-water mixture, so as to obtain a poly(N-alkylacrylamide) or poly(N,N-dialkylacrylamide) telomere of formula (I); -a step (c) of reacting, in tert-butanol, the telomer of formula (I) obtained in step (a), with an acid chloride of formula (IV) so as to obtain a solution of the macromonomer of formula (V); -a step (e) of copolymerising, in tert-butanol, the macromonomer of formula (V) resulting from step (c), with the ammonium salt of 2-acrylamido-2-methylpropanesulfonic acid and, if desired, -a step (f) of purifying the comb polymer obtained in step (e). |
