The A-B diblock copolymers with comb shape structure were prepared from styrene (St) and either methacrylate of poly(ethyleneglycol) monomethyl ether (MPEGM) or methacrylate of poly(ethyleneglycol) (HPEGM). The surface chemical analysis of the polymer at air-solid interface by means of X-ray photoelectron spectroscopy (XPS) revealed the enrichment of MPEGM for MPEGM/St and St for HPEGM/St diblock copolymers, which indicated that the end group of the side chain determined surface composition. Dynamic contact angle measurements revealed that the migration of hydrophilic poly(ethyleneglycol) at solid-water interface occurred upon immersing the film specimen in water.
