Participants

Reaction Steps

2,6-Bis(hydroxymethyl)-p-cresol (25.00 g, 0.149 moles), 4-chlororesorcinol (18.26 g, 0.127 moles), 3-methoxyphenol (3.69 g, 0.03 moles) and p-toluenesulfonic acid monohydrate (0.67 g, 0.0035 moles) were reacted four hours isolated as described in Example 3 (except an additional reslurry/filtration step was added) to yield 40.4 g novolak. See Tables 1 and 2 for glass transition and alkaline dissolution data. The ortho-, ortho-linkages of the alternating copolymers and the terminal groups were identified by 13C NMR analysis.
