HCID 69102216p-Tert-butoxystyrene styrene

Procedure

Using p-tert-butoxystyrene (81.1 g, 0.46 mole) and styrene (4.6 g, 0.04 mole), the polymerization and the treatment were carried out in the same manner as described in Synthesis Example 1, (1), to give 77.1 g of poly(p-tert-butoxystyrene/styrene) as white powders having Mw 20000 (GPC with polystyrene calibration). The polymer was found to have p-tertbutoxystyrene unit and styrene unit in a molar ratio of ca. 92:8 based on 1HNMR.
