POLYMERIC LIQUID CRYSTAL COPOLYMER COMPOUND, POLYMERIC LIQUID CRYSTAL COMPOSITION, POLYMERIC LIQUID CRYSTAL ELEMENT AND RECORDING DEVICE

摘要

PURPOSE: To obtain a polymeric liquid crystal copolymer compound highly soluble in low-boiling solvents and halogen-free solvents and desirably used to form a large-area optoelectronic material by specifying its structure. ;CONSTITUTION: This polymeric liquid crystal copolymer compound comprises repeating units represented by formula I (wherein U₁ is a polymer chain, and n₁ is 0-20) or comprises repeating units represented by formula II (wherein U₂ is a polymer chain; V is -(CH₂)_n2-, -(CH₂)_n2-A- or -(CH₂)_n2-O-A- (wherein A is an aromatic ring or an alicyclic ring; and n is 0-20). Examples of U₁ in formula I and U₂ in formula II include structures of formula III (wherein R is H, an alkyl, a halogen or a phenyl). This compound should have at least one kinds of liquid-crystal-forming repeating units as a comonomer.;COPYRIGHT: (C)1996,JPO
