摘要:
AbstractThe kinetics of formation of dibenzyl ether linkages during cure of resole‐type phenol‐formaldehyde resins was studied by the use of differential thermal analysis and infrared spectroscopy. The activation energy was 21.6 kcal./mole by the Borchard and Daniels method gives and 18.6 kcal./mole by the Kissinger method. For the same process, infrared, which shows a rather good agreement between the two different methods. The heat of reaction, determined from the area under the DTA curve for the corresponding reaction, was found to be 20.2 cal
