摘要：

Polymer pseudocrownethers based on polyphosphazene are active catalysts of nucleophilic substitution reactions. With respect to the catalytic activity, polyphosphazene is a more suitable carrier of oligo (oxyethylenes) than poly (styrene-co-divinylbenzene). With increasing length of oligo (oxyethylene) branches the catalytic activity of polymers increases. The favorable effect of the content of pseudocrownether structures is particularly visible in polymers having a longer oligo (oxyethylene) chain in those reactions in which the polymer acts as a solid cosolvent. The catalysts preserve their activity also if reused.
