Abstract
This invention relates to a novel polyol composition and a process for preparing these polyol compositions. These novel polyol compositions comprise (a) an in-situ formed polyol blend which comprises (i) one or more polyether monols and (ii) one or more polyether polyols; and (b) a polyether polyol. This invention also relates to a process for preparing an open celled, flexible polyurethane foam in which the isocyanate-reactive component comprises this novel polyol composition, and to a viscoelastic polyurethane foam wherein the isocyanate-reactive comprise the novel polyol composition.
