## 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

Films were prepared by reaction of HEMA monomer with the crosslinking agent ethyleneglycol dimethacrylate (EGDMA) at crosslinking ratios, X, of 0.005, 0.01, 0.0128, 0.025, and 0.050 mol EGDMA/mol HEMA in the presence of 40 wt. % water at 60Β°C for 12 h. These membranes were subsequently swollen in wa
## Abstract The transport of urea and other biologically interesting solutes in aqueous solution across poly(2βhydroxyethyl methacrylate) (pβHEMA) hydrogel membranes has been studied. The results show that pβHEMA membranes have a high permeability to urea due to a strong interaction between the pol
