To be more compatible with blood,polystyrene(PS) was covalently-attached with phosphorylcholine(1) via ether bond.After activated by chloromethylation reaction,the PS was constructed with compound 1 by the reaction between benzyl chloride and hydroxyl group.The existence of phosphorylcholine structure onto the surface of PS was revealed by attenuated total reflection Fourier transform infrared spectroscopy(ATR-FTIR) and 1H NMR.The contact angle measurement of grafted PS membrane indicated that the grafted f...
