Poly(ethylene glycol) monomethyl ether (mPEG) was introduced into a glycidyl methacrylate‐modified styrenic thermoplastic elastomer graft copolymer via a ring‐opening reaction with the epoxy group. The chemical compositions of the samples were confirmed by Fourier transform infrared spectroscopy, 1 H‐NMR spectroscopy, and gel permeation chromatography. X‐ray photoelectron spectroscopy, atomic force microscopy, and water contact angle measurement were used to investigate the surface properties. The results show that the molecular weight of the mPEG monomer had a great effect on the surface properties of the modified samples. The platelet adhesion and protein adsorption of the samples modified with low‐molecular‐weight mPEG were reduced dramatically relative to those of the virgin styrenic thermoplastic elastomer. © 2014 Wiley Periodicals, Inc.
