一般說明

-甲基苯乙烯是一种芳香烷基取代的苯乙烯单体,沸点相对较高。广泛用作单体,合成应用于粘合剂和高温稳定性涂料的热塑性复合树脂。还可以作为前体参与天然产物、药物和其他结构多样性化合物的区域选择性和非对映选择性合成。

應用

α-甲基苯乙烯可用于:

  • 作为单体制备“苯”单体,用于光聚合性牙科树脂复合材料,以降低其聚合收缩率。 α-甲基苯乙烯双键浓度低,适合制备低体积收缩和收缩应力弹性树脂复合材料。
  • 作为单体制备聚α-甲基苯乙烯聚合物,该聚合物可用作制造有机薄膜晶体管的添加剂。这种聚合物促进了均匀排列的半导体晶体的生长,取向显著改善。
  • 作为合成具有治疗潜力的3,4-二氢吡喃的前体。

The work was aimed at studying alpha-methylstyrene oxidation by three active Pseudomonas cultures. P. acidovorans 9 oxidized alpha-methylstyrene only to acetophenone whereas two P. aeruginosa cultures assimilated the compound entirely.
