Document Type and Number:
WIPO Patent Application WO/2011/152036
Kind Code:
A1
Abstract:
Provided are a polymer polyol from which polyurethane having a high tensile strength can be produced, and a method for producing polyurethane using a polyol component which comprises said polymer polyol. A polymer polyol (I) comprising polymer microparticles (JR) contained in a polyol (PL), said (JR) comprising an ethylenically unsaturated compound (E) as a constituting unit, wherein (PL) contains a strength-improving agent (b) as will be described hereinbelow and the volume-average particle diameter (R) of (JR) is 0.1-1.5 μm.
Strength-improving agent (b): at least one kind of a compound which is selected from the group consisting of an ester compound, a thioester compound, a phosphate compound and an amide compound and comprises, as an essential component, a divalent or higher-valent aromatic polyvalent carboxylic acid.
