Due to its superior mixing and heat exchange properties，microreactor developed in polymerizations recently has showed a great potential. The aim of this review is to summarize the applications of microreactors in free radical，ionic and stepwise polymerizations. Molecular weight and molecular weight distribution，copolymer composition and molecular structure can be better controlled in microreactors than that in traditional batch reactors. By employing microreactors，polymers with narrow molecular weight distributions can be obtained in highly exothermic polymerizations and reaction time can be drastically reduced in diffusion-controlled polymerizations. Further applications of microreactors in polymerization reactions depend on better understanding of polymerization mechanisms and microreactor characteristics，and related theoretical investigations will be of a great importance in this area.

A novel 206 nm excilamp was generated with microwave-driven Kr/I₂ mixtures as a light source，which was combined with H₂O₂（MWEL/H₂O₂）for indole and quinoline degradation in an aqueous solution. 50 mg/L of indole and quinoline can be removed entirely after 45 min irradiation with H₂O₂ dosage over 0.06 mol/L，otherwise，it can not be mineralized utterly. The increasing of irradiation time and H₂O₂ dosage or the decreasing initial concentration of target compounds all resulted in the decline of mineralization degree. The intermediates were identified qualitatively by gas chromatography/mass spectrum（GC/MS）with headspace sampling after they were extracted by rotary evaporator. FTIR is used to analyze solid precipitated in indole degradation process. The results showed that aggregation reaction occurred during indole photodegradation，as a result，5H-naphtho [2,3-c]carbazole，aliphatic alkene and ester compounds were formed. However，quinoline has gone through ring-open dissociation and oxidation degradation under MWEL/H₂O₂，and the products were hexanal，acetic acid butyl ester，1,3-dimethyl，o-xylene and 2-ethoxyethyl acetate，respectively. The rate constant of indole mineralization was inferred from kinetic equation. Two conclusions were suggested：the mineralization of indole can be approximated as apseudo-first order kinetics，and was resulted from a direct reaction with hydrogen peroxide and an indirect reaction with ·OH radical.
