Poly(2-hydroxyethyl methacrylate) gels obtained by the cross-linking polymerization using four different free-radical initiators were washed with water. Chromatographically, the eluate appeared to be a mixture of low-molecular-weight compounds and of a small amount of the high-molecularweight compon

## Abstract The wettability characteristics of the contact lens material, PHEMA, with respect to water have been determined by using the sessile drop, and the captive air bubble techniques of contact angle goniometry. It is concluded that on PHEMA gels water does not spread spontaneously. Large hys
b-Galactosidase was immobilized in/on poly(2-hydroxyethyl methacrylate) (pHEMA) membranes by two di β erent methods : adsorption on Cibacron F3GA derivatized pHEMA membranes (pHEMA-CB), and entrapment in the bulk of the pHEMA membranes. The maximum b-galactosidase adsorption on pHEMA-CB membranes was
