摘要

Epoxide compounds and phenolic compounds are reacted in the presence of phosphonium compounds represented by the formula ⊖Z'R. sup.1 R. sup.2 R.sup.3 P⊕-Z-P⊕R.sup.1 R.sup.2 R.sup.3 Z'⊖ wherein each R.sup.1, R.sup.2 and R.sup.3 is independently an aromatic group or an inertly substituted aromatic group; Z is --(C(R.sup. 4).sub.2).sub.a --; each R.sup.4 is independently hydrogen or a hydrocarbyl group containing from 1 to about 20 carbon atoms; Z' is any suitable anion and a has a value of at least 4.
