英文摘要：

A series of polyethylene glycol（ PEG） double imidazole ionic liquids have been synthesized,characterized and applied in catalyzed hydrosilylation of olefin by Rh Cl3. The effects of the amount of Rh Cl3 and ionic liquid,reaction temperature and reaction time on the reaction were investigated.Under solvent-free and low temperature,the catalysis system showed good catalytic performance.
