ABSTRACT:
The present invention provides amine/amide catalysts for use in catalyzing the formation of polyurethane. The amine/amide catalysts, which have low fugitivity due to their reactivity with isocyanates, and good catalytic activity, have the structure ##STR1## wherein Q is C.sub.z H.sub.2z+1, or (CH.sub.2).sub.n N(R.sup.3).sub.k T, T is a monovalent C.sub.1 -C.sub.4 alkyl, amino-C.sub.1 -C.sub.4 -alkyl, mono-C.sub.1 -C.sub.4 -alkylamino-C.sub.1 -C.sub.4 -alkyl, or di-C.sub.1 -C.sub.4 -alkylamino-C.sub.1 -C.sub.4 -alkyl group, or T is a divalent alkyl, amine substituted alkyl, alkylaminoalkyl, or alkoxyalkyl group which forms with the nitrogen atom shown in structure (I) to which T is attached a cyclic structure which incorporates up to 6 carbon atoms in the ring as well as the nitrogen atom shown in structure (I), which cyclic structure may be substituted with C.sub.1 to C.sub.4 alkyl;
k=0 or 1, being 1 if T is a monovalent group and 0 if T is a divalent group; R.sup.2 .dbd.H or C.sub.z H.sub.2z+1 ; R.sup.3 .dbd.C.sub.z H.sub.2z+1 ; R.sup.4 .dbd.H; R.sup.5 .dbd.H or CH.sub.3; n=2 to 6; and z=1 to 4. "n" is preferably 2 to 3 and z is preferably 1. Each R.sup.3 and T may be the same or different, as may each value of n and z. One specific preferred range of structures is those in which Q is C.sub.z H.sub.2z+1.
