Abstract
The formation of high-resilience polyurethane foam is provided by the use, as the foam-stabilizing component, of a particular class of morpholino-bearing polyalkylsiloxanes which consist essentially of: (1) monofunctional siloxy units (M.degree.) the respective silicon atoms of which have two alkyls bonded thereto, the third silicon-bonded organic group being alkyl or Q where Q is morpholinoalkyl- or morpholinoalkoxyalkyl, (2) an average of from about 0.5 to about 8 moles of difunctional dialkylsiloxy units for every two moles of M.degree., and (3) from zero up to an average of about 8 moles, for every two moles of M.degree., of difunctional monoalkylsiloxy units in which the second organic group bonded to silicon is Q, provided an average of at least about 0.5 and no more than about 8 moles of said silicon-bonded Q groups are present in the siloxanes for every two moles of M.degree.. In addition to such morpholinoalkyl- and morpholinoalkoxyalkyl-polyalkyl-siloxanes, the high-resilience polyurethane foam formulations employed in the method of the invention, contain an organic polyol reactant comprising a polyether polyol reactant having an average primary hydroxyl content of at least about 35 mole percent based on the total moles of hydroxyl groups contained in said polyether polyol. The polyol reactant may additionally conprise a polymer/polyether polyol.
