2-Methylenesuccinates (Itaconates) (2) having two 4-methoxyazobenzene moieties as paired mesogenic groups were prepared. The monomer 2 was radically homopolymerized and copolymerized with non-mesogenic monomer, dioctadecyl itaconate (DOI). Paired mesogenic homopolyitaconate exhibits a nematic phase and the copolymers of the monomer 2 with DOI also show a mesomorphic phase up to 25 mol% of DOI content. The enhancement of mesophase formation by paired mesogens is discussed.
制备了具有两个 4-甲氧基偶氮苯作为成对介原基团的 2-亚甲基琥珀酸盐(衣康酸盐)(2)。单体 2 与非介源单体--衣康酸双十八烷基酯 (DOI) 进行辐射均聚和共聚。成对介观均聚它肯酸酯表现出向列相,单体 2 与 DOI 的共聚物在 DOI 含量达到 25 摩尔%时也表现出介观相。本文讨论了成对介原对介相形成的促进作用。
