  Fl�ssigkristalle mit aliphatischen Gruppen zwischen Cyclohexanringen - Synthesen von 1,4-Bis-(4-n-alkylcyclohexyl)butanen und 4-[4-4(4-n-Alkylcyclohexyl)butyl]cyclohexylestern

  摘要：

  The synthesis of 1,4-bis-(4-n-alkylcyclohexyl) butanes (1), esters of 4-[-(4-n-alkylcyclohexyl)butyl]cyclohexanols (2) and some analogous aromatic compounds are described. The thermal stability of mesophases of these compounds are in the order of the analogous ethylene-bridged liquid crystals. The reason for this result seems to be the combination of molecular rigidity and conformational flexibility.

  The present invention aims to provide a polymerizable compound that has high storage stability without causing crystal precipitation when added to a polymerizable composition and to provide a polymerizable composition containing the polymerizable compound. A polymer film produced by polymerization of the polymerizable composition has a low haze, high thickness uniformity, low occurrence of nonuniform orientation, high surface hardness, high adhesiveness, and good appearances and fewer orientation defects even after ultraviolet irradiation. The present invention also aims to provide a polymer produced by polymerization of the polymerizable composition and an optically anisotropic body produced from the polymer.
