The influence of condensation varables, such as F/M ratio, pH and condensation temperature, on the chemical structure of liquid MF resins was studied with the aid of high resolution 13 C solid and liquid NMR, HPLC and Raman spectroscopy. These techniques can be used to obtain qualitative as well as quantitative information about the chemical composition of MF resins. Where necessary, these analytical tools
were further developed.
The degree of condensation of MF resins can be studied by quantitatively measuring the amount of water released, via 1 H NMR, or by measuring the total number of bridges via 13 C NMR....
