Reaction Steps

2,6-Bis(hydroxymethyl)-p-cresol (25 g, 0.149 moles), 4-chlororesorcinol (18.26 g, 0.126 moles) and p-toluenesulfonic acid monohydrate (0.67 g, 0.0035 moles) were heated for 5.5 hours at 65°-70° C. in 37 mL 2-ethoxyethanol. The reaction mixture was diluted with 125 mL 2-ethoxyethanol and added dropwise to 1.5 L rapidly stirring H2O. The solid was collected by filtration, reslurried in 1 L H2O and refiltered. This process was repeated twice and the solid vacuum dried to yield 38.49 g. 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.
