Paragraph 0260; 0262; 0281-0282, (2020/10/27)
PROBLEM TO BE SOLVED: To provide a production method of a polymerizable compound which hardly causes a yield decline due to alkali treatment, where discoloration hardly occurs in heat treatment of a film-shaped polymer formed from a polymerizable liquid crystal composition to which the polymerizable compound is added. SOLUTION: The invention provides a production method of a compound represented by general formula (IV). The invention also provides a production method of a polymerizable composition containing the compound, and a production method of an optically anisotropic body obtained by polymerizing the composition.

Study of activation energy and order of reaction of some liquid crystals
Mundhe
, p. 246 - 249 (2007/10/03)
Liquid crystals of the type p-phenylene-di-p-n-alkoxy benzoate have been prepared. Kissinger isothermal decomposition method has been used for determination of activation energy values of liquid crystals. Kissinger's assessment for shape index of DTA peaks is used to find the order of reaction. There is no direct relationship between the carbon atoms in terminal methylene groups and Ea values. Order of reaction value decreases with increase in heating rate upto carbon atoms 10 in the terminal methylene group but beyond this the order increases or decreases.
