| titleOfInvention |
A kind of preparation method of hydrophilic polystyrene microspheres |
| abstract |
The invention discloses a preparation method of hydrophilic polystyrene microspheres, which is characterized by comprising the following steps: the hydrophilic polystyrene microspheres of the present invention are complexed with polyvinyl alcohol macromolecules and small molecules , the formed complex is adsorbed on the surface of polystyrene microspheres, and then the residual polyhydroxyl group of polyvinyl alcohol polymer is post-crosslinked, and then the complex structure of polyvinyl alcohol type polymer is removed to obtain a surface with polyhydroxyl group. Structured polystyrene microsphere material. |
