摘要
The present invention relates to a preparation for a polyurethane foam and a polymer polyol preparation for a polyurethane foam, each of which exhibits high coloration and discoloration inhibition properties over a long period of time when stored, and to a composition for a polyurethane foam, which is excellent in storage stability and is preferable as a resin premix. The composition for a polyurethane foam of the present invention is characterized by comprising (i) at least one polyol selected from a polyoxyalkylene polyol and a polymer polyol wherein polymer fine particles obtained by polymerizing a compound having an unsaturated bond are dispersed in the polyoxyalkylene polyol, (ii) a compound having a P=N bond, (iii) an antioxidant having a hydroxyphenyl group, (iv) at least one acid selected from the group consisting of an acyclic aliphatic monocarboxylic acid of 2 to 25 carbon atoms, a hydroxycarboxylic acid of 2 to 25 carbon atoms, a polycarboxylic acid of 20 to 60 carbon atoms, a specific aromatic monocarboxylic acid, a sulfonic acid and an acid having a sulfuric acid ester group, or its salt, (v) a catalyst for polyurethane foam production and (vi) a blowing agent.
