The following conclusions arrived from studying the synthesis and properties of co-condensation of PUF resin:(1) PUF resin through the Fourier transform infrared spectroscopy and nuclear magnetic resonance spectrum(H) analysis showed that of the PUF synthetic resin under the weak-base alkaline conditions was mainly obtained by Methylol urea and Methylol phenol condensation.

In order to make PUF resin be utilized efficiently,the curing kinetics of PUF resin was studied by using FTIR spectrum and DSC,the research showed that the curing reaction of synthetic PUF co-condensation resin was mainly through the hydroxymethyl bond.
