Azobisisobutyronitrile → Styrene

Participants

Reaction Steps

300 g of p-t-butoxystyrene, 30 g of styrene, and 1.6 g of azobis-iso-butylonitrile were dissolved in 330 g of dioxane, and reacted for 12 hours under a nitrogen atmosphere at 70° C. After the reaction, unreacted monomers were removed to obtain a copolymer of p-hydroxystyrene and styrene. This resin was hydrolyzed with an acid to produce 180 g of a copolymer of p-hydroxystyrene and styrene with Mw of 18,000. NMR measurement confirmed that the molar ratio of p-hydroxystyrene and styrene was 85:15.
