Abstract
Soluble, hydrophilic polymers suitable for medical use and as blood plasma substitutes comprising low molecular weight polymer derived from at least one monomer of an acrylamide type material or a mono-ester of an acrylic type acid and a glycol which is condensed with bifunctional compounds to form a condensation polymer having increased molecular weight and enzymatically cleavable cross-links. The hydrophilic polymer is produced by polymerizing the acrylamide type material or monoester mentioned above to form a low molecular weight polymer which is then condensed with a bifunctional compound to form a high molecular weight condensation polymer having enzymatically cleavable cross-links.
