Reaktionsschritte
Similar viscosities are obtained by initially heating the polyalcohols (a) to (d) with polyphosphoric acid (= phosphoric acid dehydrated above 200° C.), resulting once again in the formation of acid semi-esters and diester mixtures through cleavage of the anhydridic phosphorus-oxygen-phosphorus bond. These acid semi-ester and di-ester mixtures are mixed with the multicomponent mixture of 1 mol of ε-caprolactam, 1 mol of trimethylol propane and 1 mol of water.
