HCID 33665(1,1'-Biphenyl)-2,3'-diol

Procedure

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