摘要：
Model compounds have been used to investigate the curing behaviour of resole phenol formaldehyde resins. These models have shown that an ortho quinone methide intermediate is very site specific, preferring to react at a free ortho site of phenols. This study also shows that phenoxy type bridges can be formed by ether exchange between a phenolic OH and an ether bridge. These results help explain some of the structures observed in cured resins.
