Polynaphtylmethacrylates (PNMA) are considered as a new class of liquid crystal (LC) photoaligning polymers. The films of PNMA irradiated with polarized UV light provide high quality LC alignment with the easy axis oriented perpendicularly to polarization direction of the exciting light. A maximal value of the azimuthal anchoring energy was estimated as 5×10-6 J/m2. It is close to the best photoaligning materials. Fries rearrangement is considered as a main photochemical reaction leading to anisotropy of PNMA layers.

Paragraph 0075; 0076, (2019/01/04)
Provided is a production method whereby corresponding carboxylic acid esters can be obtained from a variety of carboxylic acids at a high yield, even under conditions using a simple reaction operation and little catalyst and even if the amount of substrate used is theoretical. A production method for carboxylic acid ester, whereby a prescribed diester dicarbonate, carboxylic acid, and alcohol are reacted in the presence of at least one type of magnesium compound and at least one type of alkali metal compound.

Paragraph 0035; 0037-0038; 0043, (2018/11/24)
PROBLEM TO BE SOLVED: To provide a method for producing less discolored (meth)acrylic naphthyl ester at a high yield by reacting (meth)acrylic anhydride with naphthol, and to provide a method for producing (meth)acrylic naphthyl ester achieving high polymerization rate. SOLUTION: There is provided a method for producing (meth)acrylic naphthyl ester by reacting naphthol and (meth)acrylic anhydride, wherein, the production method of (meth)acrylic naphthyl ester is characterized in making a carbonate salt present in the reaction system of the naphthol and the (meth)acrylic anhydride.
