Embodiment 1

[0089] A 25 ml two-neck round bottom flask equipped with a magnetic stirrer was connected to a 2 liter oxygen-filled rubber bladder, and the flask was filled with oxygen. Then add 0.03 mmol Cu(Cl) 2 (1,4,7-triisopropyl-1,4,7-triazacyclononane) (see J.Am.Chem.Soc., 120,8529, (1998), abbreviated as Cu(tacn) ), followed by the addition of a solution of 0.6 mmol of 2-n-octadecylphenol and 0.3 mmol of 2,6-diphenylpyridine (as base) dissolved in 1.2 g of toluene. The temperature was controlled at 40°C, and the mixture was thoroughly stirred. After 48 hours, the mixture was acidified by the addition of concentrated hydrochloric acid, followed by the addition of 25 ml of methanol, and the precipitated polymer was filtered. The polymer was washed three times with 10 ml of methanol, and dried under reduced pressure to obtain a polymer. The results of the analysis of this polymer are listed in Table 1.

[0090] This polymer was subjected to NMR analysis (LA600, trade name, manufactur...

Embodiment 2 and 3

[0093] A polymer was obtained in the same manner as in Example 1 except that the reaction time was changed as in Table 1. The analytical results of these polymers are listed in Table 1.

Embodiment 2

[0094] The polymer of Example 2 was measured using a polarizing microscope (XTP-11 type with heated stage, manufactured by Nikon Corporation). As a result, when the polymer was heated from room temperature to 50°C, the transmitted luminous flux increased (optical anisotropy), however, a dark field was observed at 52°C (optical isotropy).

Abstract

An oxidation polymer of a substituted phenol, obtained by oxidative polymerization of at least one compound selected from the group consisting of a compound of formula (Ia) and a compound of formula (Ib), in which the oxidation polymer has a number-average polymerization degree of 3 or more: wherein R1 to R4 each represent a hydrogen atom and the like; provided that at least one of R1 to R4 represents a substituted or unsubstituted, saturated hydrocarbon group having 10 or more carbon atoms, and R1 and / or R4 represent a hydrogen atom; wherein R11 represents a substituted or unsubstituted, saturated hydrocarbon group having 15 or more carbon atoms, and R12 is the same as R11, or when R12 is different from R11, R12 represents a substituted or unsubstituted hydrocarbon group and the like.

Description

field of invention [0001] The present invention relates to a novel oxidized polymer of substituted phenols. Background technique [0002] Traditionally, for oxidized polymers of substituted phenols, mainly oxidized polymers of 2,6-disubstituted phenols have been considered. And recently, oxidized polymers of phenols having no substituent at the 2-position and / or 6-position (Kagaku toKogyo, Vol. 53, No. 4, pp. 501-505 (2000)) have also attracted attention. [0003] On the other hand, aromatic polymers having a saturated hydrocarbon group having a plurality of carbon atoms have been developed, and various properties regarding crystallinity, liquid crystallinity, viscoelasticity, solubility and the like of the polymer have been found. exist Macromolecule (Macromolecules), 29, 1337, (1996), the above-mentioned aromatic polyesters are described. exist Macromolecule (Macromolecules), 27, 7754 (1994), the above-mentioned polyaniline is described.
