| Abstract: | A series of narrow molecular weight distribution PS were prepared by anionic polymerization under pro-tection of inert gas, using n-BuLi as catalyst and C6H12 as solvent. The products were characterized by NMR, FT-IR and GPC. The factors affecting the molecular weight and its distribution were also investigated. At last, the application of nar-row molecular weight distribution PS was presented. |
