実験手順

27.2g (0.05 mole) of 1,1,3-tris(2'-methyl-4'-hydroxy -5'-t-butylphenyl) butane, 8.6g (0.04 mole) of diphenylcarbonate and 0.05g of potassium carbonate were reacted under N2 atmosphere at 150° C for 3 hours, and then phenol was distilled off under reduced pressure (max. 160° C/3 mm Hg) to obtain a glassy solid. Distilled phenol residue after cooling was 100% of the calculated quantity and the molecular weight of the product was 2740 (calculated value: 2824).
