Morterra and Low109,110 proposed that thermal crosslinking may occur between 300°C and 500°C where phenolic hydroxyl groups react with methylene linkages to eliminate water (Fig. 7.43). Evidence for this mechanism is provided by IR spectra which show decreased OH stretches and bending absorptions as well as increased complexity of the aliphatic CH stretch patterns in this temperature range. 

Conley showed that die primary degradation route for resole networks is oxidation regardless of the atmosphere.6 By contrast, Morterra and Low found tiiat...

The nature of hydroxyl species on alumina surface has been comprehensively reviewed also by Morterra and Magnacca [97] and by Lambert and Che [93]. Additional advances in understanding the intricate surface chemistry of y-Al203 have been made by Busca and coworkers [98,99] and Tsyganenko and Mardilovich [100].
