Beschreibung
Zusammenfassung:	The present invention relates to a rapid polymerization medical hydrogel, which is formed by polymerization of a first phase solution and a second phase solution, the first phase solution is formed by dissolving vinyl sulfone polyethylene glycol in a first buffer solution, the vinyl sulfone polyethylene glycol is four-arm vinyl sulfone polyethylene glycol or eight-arm vinyl sulfone polyethylene glycol, and the second phase solution is formed by dissolving vinyl sulfone polyethylene glycol in a second buffer solution. The second phase solution is formed by dissolving an amino compound or sulfydryl polyethylene glycol in a second buffer solution, the amino compound is cysteine, dilysine, trilysine or polyethyleneimine, and the sulfydryl polyethylene glycol is four-arm sulfydryl polyethylene glycol or eight-arm sulfydryl polyethylene glycol. The invention also relates to a preparation method of the quickly polymerized medical hydrogel. According to the quickly polymerized medical hydrogel, two different liquids,
