| 摘要 |
<p>The present invention relates to a method for preparing a polymer with a weight Mw lower than 300,000 g/mol (in particular 1,000 to 300,000 g/mol), including a step (E) of controlled radical polymerisation in which the following are placed in contact in an aqueous medium with surfactant micelles dispersed therein: ethylenically unsaturated hydrophilic monomers, found mostly within the aqueous medium; ethylenically unsaturated partially water-soluble hydrophobic monomers, separate from the preceding monomers, found at least partially within the surfactant micelles, and having solubility in the aqueous medium at least equal to that of hexyl acrylate; at least one radical polymerisation initiator; and at least one radical polymerisation control agent.</p> |
