Abstract
What is described is a polymeric hydrogel product of a stable, aqueous polymeric composition which composition forms a clear to translucent film upon application to a substrate, and includes, by weight, 5-75% of (a) a water-soluble polymer having (b) in situ-formed, substantially water-insoluble resinous particles of said polymer substantially uniformly dispersed therein, and (c) 25-95% of water, made by irradiating the composition with high energy electron beam or gamma-radiation.
