Atom transfer radical polymerization (ATRP), which can yield polymers with controlled molecularweight and low polydispersity, is an effective approach to realize living radical polymerization.
The results demonstrated that the zeolite could be effective for removing higher molecularweight (MW) organics but less effective at lower one.
结果表明：沸石能有效地去除大分子的有机物，对小分子有机物的去除效果很差。

Conclusion it is quite effective, convenient, safe, economical and commendatory to use aspirin and low molecularweight heparin in acute cerebral infarction therapy.
