Abstract

Polyol compositions comprising a polyether polyol having a molecular weight of at least 1500, a polyhydroxy alcohol nucleus having a functionality from 2 to 8, polyoxyalkylene chain segments attached to said nucleus, and a ratio of primary to secondary hydroxyl end groups of 1.5:1 to 5.5:1, and including a proportion of an effectively dispersed finely divided solid particulate material having an effective maximum particle size in dispersion of less than 75 microns, are used in the preparation of high resilience polyurethane foams to stabilize against pre-cure collapse or shrinkage. The particulate material may be selected from non-metal oxides, metal oxides, metal silicates, metal salts, solid organic or inorganic polymers, carbon and organic pigments.
