A method for synthesizing a pentafluorophenyl acrylate polymer includes bulk polymerizing a pentafluorophenyl acrylate monomer in the presence of a free radical initiator. The system includes an accumulator that is pressurized by the tensioning system as a bale is being formed. An endothelin receptor is obtained by culturing this transformant. In the phosphor treatment method of the invention, the surface region of individual phosphor particles is selectively modified by forming a highly reactive gas atmosphere by exciting gas which contains reactive gas, and exposing the phosphor to the gas atmosphere. The protection printing ink and the picture can be mixed with wax in the proportion of 10%. The chemical reducing agent or agents, generally chosen from ammonia or ammonia precursors, are introduced at a specific point in the rotary preheater kiln which has as an optimal temperature window to achieve the greatest reduction of NOx emissions.
