Process for producing polymer particles with irregular shape |
| 摘要 |
A process for producing polymer particles with an irregular shape by polymerises a water-soluble polymerizable monomer in a system comprising a hydrophobic organic solvent inert to the polymerization and an aqueous solution of the water-soluble polymerizable monomer, characterized in that the system further contains an anionic surfactant. <IMAGE> |
