Abstract

Dehydrated aqs. gels of natural and/or synthetic cpds. are made so that they can be rehydrated completely by treating an aqs. gel of the cpd. with an aqs. soln. of polyalcohol formed by polymerising ethyleneglycol, saccharose or vinylpyrrolidone, removing the gel from the soln. and dehydrating the known by e.g. freeze drying. Applicable to gelose, agarose, gelatine, albumin, acrylamide etc.
