Abstract
Poly (p-phenylacetyl) was synthesized through homogeneous Friedel-Crafts polymerization of chloride phenylactyl catalyzed by 1,3-dialyklimidazolium and alkylpyridium/AlCl_3 ionic liquid. The experimental results indicate that chloride phenylactyl polymerization temperature can be controlled 20~25 ℃, the yield of poly(p-phenylacetyl) is over 90% and its Mw/Mn reachs 16 500/7 890.The analytic results indicate that Friedel-Crafts polymerization takes place in para-position.
