Title:

1,6-HEXANEDIOL COMPOSITION AND POLYMER

Document Type and Number:

WIPO Patent Application WO/2024/018979

Kind Code:

A1

Abstract:

The purpose of the present invention is to provide a 1,6-hexanediol composition that can improve the hydrolysis resistance of a polymer obtained using the 1,6-hexanediol composition as a reaction raw material, and to provide a polymer obtained by reacting the 1,6-hexanediol composition. The present invention relates to a 1,6-hexanediol composition containing 1,6-hexanediol and/or a 1,6-hexanediol derivative and an alkali metal element, wherein the total content of the alkali metal is 0.1-1000 mass ppm relative to the total amount of the composition and the acid value of the composition is in the 0.001-1.0 mg KOH/g range.
