Reaction Conditions

Reaction Steps

152 g of bisphenol A, 63 g of a diglycidyl ether of bisphenol A, having an epoxide equivalent weight of 189, and 0.1 g of tributylphosphine were heated at 160° C. for 1 hour. After this time, epoxide was no longer detectable and a chain-extending 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.
