Summary
The phase behaviour of the glass transition in aqueous hydroxyethyl starch solutions was studied using differential scanning calorimetry. During rewarming, the glass transition in a quenched solution containing 62.4 weight % hydroxyethyl starch begins at the unexpectedly low temperature of -110 deg C. The transition is very broad as usual for cross-linked systems, finishing at -50 deg C with the crystallization of water from the previously amorphous material. Conclusions are given.
