脲醛树脂结构研究进展

Abstract

Abstract:

Over the past 20 years,many efforts have been expended to elucidate the structure of ureaformaldehyde (UF)resins for obtaining more effective UF resin adhesives with optimized strucutres.Several modern analytical tools and techniques have been applied as they become available.Fourier transform infrared spectroscopy (FTIR)and ¹³C nuclear magnetic resonance(¹³CNMR)are the most useful and powerful tools.Characterization of the structure of UF resins by ¹³C NMR of their solution is well established and is the most important technique,and it is the best method at molecular level of characterizing and documenting the variations in resin chemistry for UF adhesives.This paper gives a review on history,methods and results about the study on the structure of UF resins.

Key words: Urea-formaldehyde resins, Structure, Fourier transform infrared spectroscopy (FTIR), ¹³C Nuclear mag netic resonance (¹³C NMR)
