Title:
METHOD FOR PRODUCING POLYTHIOL COMPOSITION, METHOD FOR PRODUCING POLYAMINE COMPOUND AND APPLICATIONS OF THESE
Document Type and Number:
WIPO Patent Application WO/2024/048389
Kind Code:
A1
Abstract:
This method for producing a polythiol composition comprises a production step in which a polythiol composition is produced by decomposing a thiourethane resin by means of a decomposer that is represented by formula (1) or formula (2). In formula (1), each of R1 and R2 independently represents a hydrogen atom, an alkyl group having 1 to 3 carbon atoms or an amino group (excluding the cases where both R1 and R2 are amino groups). In formula (2), R3 represents an alkyl group having 1 to 3 carbon atoms.
