  • Composition for polyurethane foam containing polyrotaxane, polyurethane foam derived from composition, and method for producing polyurethane foam
    Patent number: 11053367
    Abstract: The present invention provides: a polyurethane foam having excellent viscoelastic characteristics and/or excellent feeling; a composition for the polyurethane foam; and a method for producing the polyurethane foam. The present invention provides a composition for a polyurethane foam, the composition containing: (A) a polyol having three or more OH groups; (B) a compound having two or more isocyanate groups; and (C) a polyrotaxane obtained as a result of arranging, on both ends of a pseudo-polyrotaxane formed through skewering-like inclusion of a linear molecule through the openings of cyclic molecules, stopper groups so that the cyclic molecules do not dissociate from the pseudo-polyrotaxane.
    Type: Grant
