There is disclosed a cross-linked hyaluronate compound obtained by reacting a sodium hyaluronate compound with a polfunctional aziridine compound as a cross-linking agent. The polyfunctional aziridine compound was added to hyaluronan of various molecular weights in an equivalent ratio of HA/AZ of 1:1 to 1:10, preferably, 1:3 to 1:10, more preferably, 1:3 to 1:5; most preferably 1:4 to 1:5. The polymeric hydrogel compounds obtained are useful to prevent the formation of post-operative adhesions, designing tissue engineering applications, and the like.
A process for preparing trisaziridinomethane (I)
by reacting aziridine with chloroform, wherein the molar ratio of aziridine to chloroform is not more than 3:1.
