Title:
THRMOTROPIC LIQUID CRYSTAL POLYPEPTIDE
Document Type and Number:
Japanese Patent JPH0234631
Kind Code:
A
Abstract:
PURPOSE:To obtain the title polypeptide which shows a thermotropic liquid crystal property, forms a liquid crystal below a specified temperature and can be used as a temperature-indicating material, a notch filter, an optical recording material or the like, having a structure of a specified formula. CONSTITUTION:The title polypeptide is a beta-benzyl aspartate/gamma-alkyl glutamate copolymer of the formula (wherein R is a 5-30 C linear or branched alkyl; m/n is 0.1-3; and m+n is 10-5000). This copolymer shows a thermotropic liquid crystal property; its liquid crystal temperature range can be adjusted by changing the number of the carbon atoms of the alkyl group or the comonomer ratio, and therefore a copolymer which forms a liquid crystal at a temperature lower than 100 deg.C can be formed. This copolymer is applicable to a temperature- indicating material, a notch filter, an optical recording material or the like.
