中文摘要：

基于聚合物试剂合成的后处理简单，纯化方便和易于回收的特点，分别用聚苯乙烯和聚乙二醇树脂为载体进行几个手性奎宁催化剂的固相和液相组合合成，考察了MPEG5000负载的奎宁催化剂沉降率的影响因素．

英文摘要：

Several polymer - supported quinines as chiral catalysts were synthesized from polystyrene and polyethylene glycol as supporter. The synthesis has the advantages of easy purification and recovery. The factors to influence the sedimentation of MPEG - supported quinine were also discussed.
