Participants

Conditions

Temperature: 170 °C

Procedure

375 g. (1.8 moles) of p-tert-octylphenol, 75 g (0.8 mole) of phenol, 50 g (0.22 mole) of 4,4'-isopropylidene-biphenol (bisphenol A), 215 g (2.65 moles) of 37% formalin, 10 g of oxalic acid and 100 g of xylene were put into a reactor, and they were refluxed for 7 hours at the boiling point of the water-xylene azeotrope. The reaction mixture was then heated to 170° C. while removing water and the solvent, thereby giving a p-tert-octylphenol/phenol/bisphenol A/formaldehyde co-condensate having a softening point of 85° C.
