The products resulting from contacting an organic phosphine or arsine with an inorganic acid having a weak nucleophilic anion provide for relatively stable compositions when admixed with a compound containing an average of more than one vicinal epoxide group per molecule and which optionally contains a compound containing an average of more than one phenolic hydroxyl group per molecule.
有机膦或砷化氢与具有弱亲核阴离子的无机酸接触后产生的产物,在与平均每分子含有一个以上邻位环氧基团的化合物混合时,可提供相对稳定的组合物,该化合物还可选择含有平均每分子含有一个以上酚羟基的化合物。
