Participants

Reaction Steps

2,6-Bis(hydroxymethyl)-p-cresol (30 g, 0.178 moles) (BHMPC), 4-chlororesorcinol (see Table 3), 4-methoxyphenol (see Table 3), and p-toluenesulfonic acid monohydrate (0.8 g, 0.0042 moles) were reacted in 60 ml 2-ethoxyethanol at 90°-95° C. for approximately 4 hours. The solutions were diluted with 250 mL of 2-ethoxyethanol and added dropwise to 2.4 L rapidly stirring H2O. The polymer was collected by filtration, washed 3-4 times with H2O and vacuum dried. See Table 3 for yields. See Tables 1 and 2 for glass transition and alkaline dissolution data.
