Abstract: Amine-containing amide derivatives of polyethers, and the use of such materials as catalysts in manufacture of polyurethane foam. The derivatives may be represented by the general formula ##STR1## wherein: R is CH.sub.2 when the amino-amide-containing moiety is located on an end of polyether chain, and is C.sub.2 H.sub.4 or CH.sub.2 CH(CH.sub.3) when the aminoamide-containing moiety is located along a polyether chain; R' is H, an alkyl group of 2-4 carbon atoms, or R"--N(R"').sub.2 ; R" is alkylene of 2-6 carbon atoms, phenylene, or C.sub.2 H.sub.4 N(CH.sub.3)C.sub.2 H.sub.4 ; R"' groups individually are alkyl groups of 1-18 carbon atoms or phenyl, or the R"' groups on a given nitrogen atom are 2-carbon alkylene moieties joined together by a divalent linking atom X to form a six-membered ring wherein X is --O-- or >N--R*, and R* is H or an alkyl group of 1-18 carbon atoms; and n is 1-6.

Abstract: Siloxane-polyether copolymer surfactants for manufacture of high resiliency polyurethane foam which are capped with t-butyl groups on the ends of the polyether blocks, polyurethane foam compositions containing such surfactants, a method for making polyurethane foam using such surfactants, and polyurethane foam made the method are disclosed and claimed. The t-butyl-capped surfactants afford improved surfactant potencies and foam breathabilities relative to the commonly-employed methyl-capped surfactants.
