| Abstract: | A series of narrow molecular mass distribution polystyrene (PS) were prepared by anionic polymerization under the protection of inert gas, using n-buLi as initiator, C6H12 as solvent with simple treatment, THF as promoting agent. The products were characterized by 1H-NMR, IR and GPC, and the main factors affecting on the molecular mass and its distribution of PS were also discussed. |
