N-（2-Hydroxypropyl） methacrylamide copolymer-5-fluorouracil （PHPMA-FU） conjugates were synthesized by a novel and simplified synthetic route, and characterized by UV, FTIR and HPLC analyses. The conjugated content of 5-fluorouracil （5-FU） was 3.41 ± 0.07 wt%. The stabilities of PHPMA-FU conjugates under different conditions were studied. The results showed that HPMA copolymer was a potential carrier for tumor-targeting delivery of 5-FU.
