Phenolic resins (III) - Solid State Structures and Thermal Properties of Cross-linked Phenolic Resins

Non-destructive, solid state physicochemical techniques were used to analyze the structure of phenolic resins prepared with precise syntheses and thermal parameters. The results obtained with solid state 13C NMR (CP/MAS) and FTIR were analyzed and related to the thermal characteristics of the networks (DSC and TGA/FTIR). The data were correlated with parameters and conditions of syntheses of resols and of the initial prepolymers.
