実験手順

152 g of bisphenol A, 63 g of a diglycidyl ether of bisphenol A having an epoxy equivalent weight of 189 and 0.1 g of tributylphosphine were heated at 160° C. for 1 hour. Afterwards the epoxy was no longer detectable, and a chain-extended diphenol had formed. 53.8 g of isopropanol, 129 g of di-n-butylamine, 31.5 g of paraformaldehyde and 17.6 g of isobutanol were added and the mixture was heated at 80° C. for 2 hours. The product had a solids content of 80% by weight.
