Study on the Recycle of Phosphous Containing Polymers

反应(1)-(3)研究了含磷聚合物的制备和循环体系。在三乙胺存在下，试剂1与试剂2反应生成亚膦酸根3。该化合物3自身聚合得到含磷聚合物4。该聚合物与丙酮在高温下反应生成丙酮加合物5。加合物为单体。

The preparation of phosphous containing polymers and the system for recycle have been investigated as shown in Reaction(1)-(3).Reagent 1 reacted with Reagent 2 in the presence of triethyleamine to give phosphinate 3. This compound 3 polymerized itself to afford phosphous containg polymer 4. The polymer reacted with acetone at high temperature to give the acetone adduct 5. When the adduct was heated at high temperature, the adduct was decomposed to give the polymer 4 again. The adduct is a monomer.
