Sulfonated dimethyl fumarate (SDMF) was prepared with dimethyl fumarate (DMF) and sodium hydrogensulfite (NaHSO 3 ). Sodium sulfonate side-chain poly-(ethylene oxide) (SPEO) was synthesized by grafting sodium sulfonate onto the chain of PEO with molecular weights of 400, 600, 800, and 1000. SPEO was

Adsorption of proteins (fibrinogen, albumin, and gamma globulin) from plasma onto surface-modified PUS (PU-PEO, PU-SO,, and PU-PEO-SO,) was evaluated. Adsorbed fibrinogen at steady state decreased in the order PU-SO, > PU > PU-PEO-SO, > PU-PEO, suggesting that sulfonate groups have specific high aff
Graft copolymers containing poly(ethy1ene oxide) side chains attached to a polyethylene backbone were prepared by coupling of poly(ethy1ene-co-acrylic acid) (PEAA) and poly(ethy1ene oxide) monomethyl ethers (MPEO) by esterification in o-xylene a t 14OoC. The MPEO side chains had molecular weights of
