摘要:
The invention relates to a method for the preparation of a hydroxyalkyl starch derivative which comprises reacting hydroxyalkyl starch (HAS) via the optionally oxidized reducing end of the HAS with the amino group M of a crosslinking compound which, apart from the amino group, comprises a specifically protected carbonyl group, namely an acetal group or a ketal group.
