聚合物作为材料早就应用在工业中,至于其化学反应直到五十年代还研究得比较少,而最近十年来聚合物试剂作为新方法应用于有机合成中颇有发展。“聚合物试剂”是以聚合物作为较低分子量试剂的载体,在合适的溶剂中使聚合物试剂与溶解的作用物反应。根据不同的情况反应产物或是溶解在溶液中,或是与聚合物相结合。如为后一种情况,则需将产物从聚合物上断裂下来。

Polymers have long been used in industry as materials, and their chemical reactions were relatively poorly studied until the 1950s, and polymer reagents have been developed as new methods for organic synthesis in the last decade. A “polymeric reagent” is a polymer that acts as a carrier for the lower molecular weight reagent, reacting the polymeric reagent with the solubilized reagent in a suitable solvent. Depending on the circumstances the reaction product is either dissolved in solution or combined with the polymer. In the latter case, the product must be broken off from the polymer.
