The adsorption of human γ‐globulin on polymer surfaces having various chemical and physical structures was studied. The γ‐globulin adsorption on the crosslinked, rigid polymers of polyethyleneglycol dimethacrylate was considerably affected by the length of oxyethylene chains, in which the hydrophilicity of the polymers increased as the oxyethylene chains lengthened. The γ‐globulin adsorption on the rigid polymers of tetraethyleneglycol dimethacrylate (or diacrylate) was lower than other soft polymers such as hydrogel, owing to the presence of oxyethylene chains. The polymer having a porous structure appeared to be a high adsorption material for the γ‐globulin and the degree of the adsorption varied with pore size.
