As a large city advanced, the urban environment is becoming an issue. The contribution of vehicle emissions in air pollutants was very high according to the clean air policy support system (CAPSS). In order to improve the air quality in large cities, it is necessary to establish improvement measures by sources, analyzing the air quality of roadside. We divided Bucheon city into 4 regions to investigate the roadside pollutants of each district using the mobile laboratory (ML) and air quality monitoring station (AQMS). ML was used to measure pollutants emitted from vehicles and AQMS data was used as a comparison group of ML data. As a measurement result of pollutants in the roadside, the concentration of air pollutants in industrial & engineering complex area was the highest and concentration of air pollutants in residential & forest complex area was lower. By street, Bucheon-ro, Sinheung-ro, Sosa-ro, and Gyeongin-ro were identified as high concentrations. Therefore, further researches on preparing management measures for roads in the hot-spot area are needed.

The structure-controlled α, ω-diiodo-poly(vinyliene fluoride-co-hexafluoropropylene) was polymerized by "pseudo-living" free-radical polymerization using iodine transfer polymerization, which are one of the controlled telomerization methods. The molecular weight of the polymer was increased linearly with polymerization time and [monomer]/[iodide] ratio and the polymer showed a narrow molecular weight distribution(PDI<1.3). Because the molecular weight was below 10,000 g/㏖, these copolymer can be used as telechelic fluorinated prepolymer. The chain-end structure of α, ω-diiodo-poiy(vinyliene fluoride-co-hexafluoropropylene) was consisted of both -CH₂CF₂-I and -CF₂CH₂-I. HFP contents in the polymer(10∼30㏖%) could be controlled by changing monomer feed ratio.
