Hydroxyalkyl starch derivatives and process for their preparation |
(57) The invention relates to a method for the preparation of a hydroxyalkyl starch derivative
which comprises reacting hydroxyalkyl starch (HAS) via the optionally oxidised 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.
