Liquid crystal composition

Abstract

Abstract PURPOSE:A liquid crystal compsn. stable to water for a long period of time and suitable for a display device, etc., which is obtd. by mixing a hydroxyl group- contg. polymer, an org. compd. contg. a straight-chain hydrophobic group and a quaternary ammonium group, and a borate. CONSTITUTION:A polymer (A) having a repeating unit of formula I, such as saponified ethylenevinyl acetate copolymer or polyvinyl alcohol, an org. compd. (B) having two or three straight-chain hydrophobic groups or at least one straight-chain hydrophobic group contg. a rigid portion in the chain and having a quaternary ammonium group, such as a compd. of formula II, and a borate (C) such as Na orthoborate are mixed to prepare the purpose liquid crystal compsn. It is pref. to mix the components A, B and C in such a proportion that the wt. ratio of A to B is 0.1-0.9 and the equivalent ratio of C to the repeating unit of formula I in A is 0.005-0.1.
