METHOD FOR PRODUCING POLYTHIOL COMPOSITION, POLYTHIOL COMPOSITION, COMPOSITION CONTROL SYSTEM FOR THIOURETHANE RESIN STARTING MATERIAL, AND APPLICATIONS OF THESE

Document Type and Number:

WIPO Patent Application WO/2023/153484

Kind Code:

A1

Abstract:

The present invention provides a method for producing a polythiol composition, the method comprising: a step for generating a polythiol composition (S), which contains two or more polythiol compounds, by reacting a composition X that contains a thiourethane resin; and a step for producing a polythiol composition (T) from the polythiol composition (S) by adjusting the content of at least one polythiol compound contained in the polythiol composition (S).
