Reaction Steps
2,6-Bis(hydroxymethyl)-p-cresol (25.00 g, 0.149 moles), 4-chlororesorcinol (13.96 g, 0.09 moles) and p-toluenesulfonic acid monohydrate (0.67 g, 0.0035 moles) were reacted four hours isolated as described in Synthesis Example 3 to yield 35 g of 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.
