4-Ethenylphenyl acetate → p-Acetyloxystyrene p-tert-butoxystyrene

Participants

Reaction Steps

Using 48.6 g (0.3 mol) of p-acetyloxystyrene, 17.6 g (0.1 mol) of p-tert-butoxystyrene and a catalytic amount of 2,2'-azobis(2-methylisovaleronitrile), the procedure of (1) of Preparation Example 3 was carried out for reaction and after-treatments to obtain 59.7 g of poly(p-tert-butoxystyrene/p-acetyloxystyrene) as white powdery crystal. P-acetyoxystyrene unit/p-tert-butoxystyrene unit molar ratio in the polymer≈3:1 (1NMR). Mw≈10,500; Mw/Mn=1.32 (GPC with polystyrene calibration).
