Abstract
In order to improve resin physical properties such as heat resistance (glass transition temperature) of a resin such as polyester obtained from 2,2′-bis(carboxymethoxy)-1,1′-binaphthyl, provided is a composition for a resin raw material containing a compound represented by formula (1) as a component A and a compound represented by formula (2) as a component B, wherein their composition ratios are in ranges wherein the component A is present in an amount of 98.0 area % or more and 99.99 area % or less, and the component B is present in an amount of 1.50 area % or less, relative to the total amount of all components detected at a wavelength of 280 nm by high-performance liquid chromatography analysis using a UV detector.
Claims1
A resin raw material composition, comprising:
- a compound represented by formula (1) as a component A, and
- a compound represented by formula (2) as a component B;
- and
- having their composition ratios in the following ranges:
- composition ratios:
- the component A is present in an amount of 99.0 area % or more and 99.99 area % or less, and the component B is present in an amount of more than 0 area % and 1.00 area % or less, relative to a total amount of all components detected at a wavelength of 280 nm by high-performance liquid chromatography analysis using a UV detector;
- wherein R represents an alkyl group having 1 to 8 carbon atoms.
