Crosslinked poly(N-vinylpyrrolidone) (PVPy) beads were irradiated with ␥-rays in air from a 60 Co source. Preirradiated beads were grafted with polyacrylamide by refluxing with acrylamide in water or dioxane. Conditions for optimum grafting were determined under a variety of reaction parameters, suc

## Abstract Poly(__N__‐vinylpyrrolidone)s with 2–20 mol% DVB, NNMBA, HDODA and TTEGDA crosslinkings were prepared by suspension polymerisation. The binding of Rose Bengal by these poly(__N__‐vinylpyrrolidone)s was followed by a batch equilibration method. In order to optimise the conditions of dye
