Composition for polyurethane foam, preparation for polyurethane foam, polymer polyol preparation for polyurethane foam, production processes therefor, and polyurethane foam

摘要

This 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 comprises (i) at least one polyol, (ii) a compound having a P═N bond, (iii) an antioxidant having a hydroxyphenyl group, (iv) at least an acid and/or its salt, (v) a catalyst for polyurethane foam production and (vi) a blowing agent.
