ABSTRACT:
A particular class of morpholino-bearing polyalkylsiloxanes are provided 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.; 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.. The morpholinoalkyl- and morpholinoalkoxyalkyl-polyalkylsiloxanes are generally useful as surfactant providing compositions and find particular application as foam-stabilizing components of high resilience polyurethane foam formulations in which the organic polyol reactant comprises 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 siloxanes of the invention are also useful as surfactant components of high resilience foam formulations in which the polyol reactant additionally comprises a polymer/polyether polyol.
