摘　　要：利用反相悬浮聚合法制备了微米级聚甲基丙烯酸β-羟乙酯(PHEMA)微球,然后用环氧氯丙烷(ECH)对微球表面进行了化学改性,将环氧基团引入微球表面;再利用环氧基与胺基之间的开环反应,实施了聚乙烯亚胺(PEI)的接枝聚合,制得了接枝微球PEI-PHEMA。静态吸附实验结果表明,在氢键作用力的驱动下,接枝微球PEIPHEMA对尿酸具有较强的吸附能力,且吸附能力随PEI接枝度的增大而增加,最大吸附量可达到81.60 mg/g。Microsphere PHEMA were preparated via inverse suspension polymerization method, it was chemically modified with epcxy chloropropane ;PEI was then grafted via the ring-opening reaction between the epoxy groups and the amino groups of PEI, to form material of PEI-PHEMA. Static adsorption experi- ment results showed that grafted microsphere PEI-PHEMA can produce strong adsorption force by hydro- gen bond,the adsorption amount was increased with the increase of grafted PEI and the max adsorption capability can be 81.60 mg/g.
