and low protein binding characteristics in application the negma monomers may be polymerized with or without crosslinkers of diacrylic species such as tegda tetraethylene glycol diacrylate by thermal uv or other suitable initiation activation polymerization methods known in the art it should be readily apparent to one skilled in the art that other species of crosslinking agents may be utilized in accordance with the present invention preferably the crosslinker is a difunctional monomer with hydrophilic units for example another useful diacrylate monomer is polyethylene glycol diacrylate which offers the same flexible u2014 ch 2 u2014 ch 2 u2014 o u2014 linkages such as peg 200 dimethacrylate peg 400 dimethacrylate and peg 600 dimethacrylate also known as peg200dma peg400dma and peg600dma respectively peg200dma peg400dma and peg600dma are also not considered to be carcinogenic the thermal stability of the membrane coatings constructed in accordance with the present invention were tested and compared with a membrane treated similarly with hpa sodium chloride solutions of about 15 and about 20 were used to increase the surface tension of water thus making the wettability test more discriminating the protein binding tendencies were measured by obtaining a liquid sample of flow through protein solution recovery and testing a solid sample of protein on membrane a luminance spectrophotometer ls50b perkin elmer was used to measure the fluorescence intensity of fluorescein tagged bovine serum albumin bsa the i 125 bsa was also used as.
