The anion exchange resin used in Example 7 was regenerated by washing with 500 ml of a 4% aqueous caustic soda solution and then with methanol and acetonitrile to remove water. 0.43 g (0.005 mol) of methacrylic acid and 1.39 g (0.005 mol) of triphenylmethyl chloride were dissolved in methylene chloride and reacted together batchwise in the presence of the above regenerated resin to give 1.59 g (yield: 96.0%) of triphenylmethyl methacrylate.
