✦ Synopsis

A styrene-butadiene-styrene triblock copolymer SBS-g-DMAEMA membrane increased with an increase in (SBS) membrane was prepared by solvent casting. Grafting the degree of grafting. By using Kaelble's equation and the of dimethyl amino ethyl methacrylate (DMAEMA) to this contact angle data, the surface tension of SBS-g-DMAEMA SBS membrane was subsequently conducted by ultraviolet was determined. It was found that with an increase in the radiation-induced graft copolymerization without degassing degree of grafting, the surface tension and water content of to obtain a SBS-g-DMAEMA copolymer membrane. The graft SBS-g-DMAEMA membrane increased, whereas the contact copolymer was characterized by infrared spectroscopy and angle decreased. The amount of absorption of albumin and scanning electron microscopy. The degree of grafting and fibrinogen decreased with an increase in amount of grafting. the mechanical properties of SBS and SBS-g-DMAEMA were

However, there was a minimum for the adsorption of promeasured. Contact angle, water content, and protein absorp-teins in the SBS-g-DMAEMA membrane.
