| titleOfInvention |
Use, as thickening agent, of a salty aqueous formulation of a water-soluble cross-linked and hydrophobically-modified acrylic copolymer |
| abstract |
The invention relates to the use, as a thickening agent, of an aqueous solution particularly rich in salts of a water-soluble or alkali-soluble copolymer comprising (in weight): a) 30% to 45% of (meth)acrylic acid; b) 50% to 60% of acrylamide and/or N-methylol and/or an acrylic ester; c) 2% to 10% of a hydrophobic monomer of the formula R 1 - (R2O)m — R 3 , where R 1 is a polymerizable unsaturated function, R2O is an alkylene oxide group having 1 to 6 carbon atoms, m is an integer between 20 and 50, R 3 is a linear alkyl chain including at least 16 and at most 26 carbon atoms; d) 0.1% to 4% of at least one cross-linking agent that preferably consists of ethyleneglycoldimethacrylate (EDMA). |
