Document Type and Number:
WIPO Patent Application WO/2017/208865
Kind Code:
A1
Abstract:
[Problem] To provide: a method for producing a polyurethane that is easily handleable and is easily controlled in terms of polymerization, while having low halogen content; an epoxy carboxylate composition; a polyurethane; and a polyurethane resin composition.
[Solution] A method for producing a polyurethane according to the present invention comprises: a first step wherein an epoxy carboxylate compound (X) is obtained by reacting (a) an epoxy compound that has a halogen atom content of 10 ppm by mass or less, while having two epoxy groups in each molecule and no hydroxyl group, (b) an unsaturated aliphatic monocarboxylic acid that has an ethylenically unsaturated group in each molecule, while having no aromatic ring, and (c) an aromatic monocarboxylic acid that has no ethylenically unsaturated group in each molecule; and a second step wherein the epoxy carboxylate compound (X) obtained in the first step is reacted with a diisocyanate compound (Y).
