Reaction Steps

About 3.56 g (0.02 mol) t-butyltoluenediamine was dissolved in about 30 mL ethyleneglycol monopropyl ether. About 2.4 mL glacial acetic acid was added followed by about 1.98 g (0.018 mol) hydroquinone, about 0.22 g (0.002 mol) catechol (chemical name 1,2-dihydroxybenzene), and about 0.2 g copper sulfate pentahydrate. About 10 drops of 1% hydrogen peroxide was added and oxygen was passed for about 5 hours, at a rate of about 40 cc/min. When the reaction was over, about 1.7 g sodium hydroxide, dissolved in about 3 mL of water was added and the mixture was stirred for about 15 min. Reaction product is obtained by pouring the reaction mixture into water and filtering the precipitated polymer and drying it in vacuo.
