Improved polycarboxylic acids |
| abstract |
The present invention relates to a process for thenpreparation of crosslinked polymers and copolymers ofnacrylic acid and methacrylic acid of formulan nwhereinn R 1 is hydrogen or methyl. nSaid process, using ethyl formate as solvent, allows tonobtain polymers having low residue of monomer and ofnsolvent and with higher thickening capacity. |
