The novel poly(vinyldiphenylphosphine) could be easily prepared by using the reactions of the cheap poly(vinyl chloride) with sodium phosphides. Poly(vinyldiphenylphosphine) is soluble in common solvents while its corresponding phosphine oxide is hardly soluble in the solvents. Taking advantage of this different solubility, poly(vinyldiphenylphosphine) could be used as a soluble phosphinopolymer for the Wittig reactions. The reactions could take place efficiently to produce the corresponding olefins while the isolation of the products were simple since the resulted poly(vinyldiphenylphosphine oxide) was not soluble in the solvent and could be easily removed by filtration.

通过使用廉价的聚氯乙烯与磷化钠的反应，可以轻松地制备新型聚（乙烯基二苯基膦）。聚（乙烯基二苯基膦）可溶于普通溶剂，而其相应的氧化膦几乎不溶于溶剂。利用这种不同的溶解度，聚（乙烯基二苯基膦）可以用作Wittig反应的可溶性膦基聚合物。反应可以有效地进行以生产相应的烯烃，而产物的分离是简单的，因为所得的聚（乙烯基二苯基膦氧化物）不溶于溶剂，并且可以容易地通过过滤除去。
