Disclosed is a mixture containing compound (I) and polymerizable compound (II) wherein compound (I) accounts for 50 mol% or more of the entire mixture and 1,4-cyclohexanedicarboxylic acid accounts for less than 5 mol% of the entire mixture; a method of producing the mixture which includes reacting in a water-immiscible organic solvent 1,4-cyclohexanedicarboxylic acid dichloride with compound (IV) in the presence of a base, and washing the obtained reaction solution with a weakly acidic buffer solution; etc. The disclosure provides mixtures useful for low-cost production of polymerizable compounds which have low melting points suitable for practical use, show superior solubility to general-purpose solvents, can be produced at low costs, and allow for provision of optical films capable of uniform polarized light conversion over a wide wavelength range, and methods of producing the mixtures.
where A represents hydrogen, methyl group or chlorine, and n represents an integer of 1 to 20.
本发明公开了一种含有化合物(I)和可聚合化合物(II)的混合物,其中化合物(I)占整个混合物的50mol%或以上,1,4-环己烷二甲酸占整个混合物的5mol%以下;一种生产该混合物的方法,包括在碱存在下,在不溶于水的有机溶剂中使1,4-环己烷二甲酸二氯化物与化合物(IV)反应,并用弱酸性缓冲溶液洗涤得到的反应溶液;等等。本公开提供了可用于低成本生产可聚合化合物的混合物,这些混合物具有适合实际使用的低熔点,显示出优于通用溶剂的溶解性,可以低成本生产,并且可以提供能够在宽波长范围内进行均匀偏振光转换的光学薄膜,以及生产这些混合物的方法。
其中 A 代表氢、甲基或氯,n 代表 1 至 20 的整数。
