1-(Tert-butoxy)-4-ethenylbenzene → 4-Methoxystyrene

Participants

Reaction Steps

p-Methoxystyrene was polymerized in the same manner as in Example 25 and 25 ml (0.26 mole/1) of p-tert-butoxystyrene was thereafter added to the reaction mixture and further polymerized therewith at an elevated temperature of 25° C. Subsequently, methanol (330 mmoles/l) containing a small amount of ammonia water was added to the reaction system to terminate the polymerization and obtain a mixture containing a polymer. The mixture was washed first with a hydrochloric acid aqueous solution (8 vol. %) and then with water, followed by evaporation for the removal of the solvent, etc. to collect the polymer.
