Disclosed are a hydrogel of a mercapto-modified macromolecular compound and a preparation method therefor. The preparation method comprises combining the mercapto-modified macromolecular compound with an acrylated macromolecular compound and/or an acrylated micromolecular crosslinker, wherein the mercapto-modified macromolecular compound can be crosslinked with the acrylated macromolecular compound and/or the acrylated micromolecular crosslinker under physiological conditions to form the hydrogel. Due to the rapid mercapto-vinyl crosslinking reaction, the formed hydrogel system can be quickly gelled in situ after being injected into the body. The hydrogel is thus suitable for use in the fields of biomedicine, medical cosmetic plastic surgery and cosmetics. |
