Procedure

Using 30.0 g (0.28 mol) of p-cresol, 30.0 g (0.28 mol) of m-cresol and 40.5 g (0.50 mol) of a 37% formaldehyde solution, the procedure of Preparation Example 23 was carried out for reaction and after-treatments to obtain 38.4 g of p-cresol/m-cresol/formaldehyde polycondensate as slightly white waxy crystals. Mw≈6,600; Mw/Mn=6.82 (GPC with polystyrene calibration).
