Catalyzed Activity of SO_4~(2-)/TiO_2 Solid Superacid for β-Pinene Polymerization

Polymerization of β-pinene catalyzed by SO42-/TiO2 solid superacid had been studied.The results showed that the catalyst had better activity to β-pinene polymerization under near room temperature.When the mass part of catalyst was 30% (β-pinene) and the polymerization temperature at 20 ℃,duration time 6 h,the yield of poly(β-pinene) resin was 24.6%.
