摘要

<正> Poly N-isopropyl acrylamide （abbreviated as PNIPA） as a kind of thermally sensitive hydrogel is utilized to concentrate Bovin Serum Albumin （BSA） solution. In order to decrease its surface adsorption to BSA in aqueous solution

surface layer grafting of the gels by radiation technology was carried out. The results showed that hydroxyl propyl methacrylate （HPMA） grained gel exhibited a low level of BSA adsorption and still kept the original thermally sensitive properties of PNIPA hydrogels.
