| Abstract: | A series of narrow molecular weight distribution PS was prepared by anionic polymerization under the protection of inert gas,with n BuLi as initiator,C 6H 12 as solvent,and THF as accelerating agent The products were characterized by 1H NMR ,FT IR and GPC,and the main factors that had effect on the molecular weight and its distribution of PS were also discussed |
