REACTIVE AMINE CATALYSTS AND THEIR USE IN POLYURETREACTIVE AMINE CATALYSTS AND THEIR USE IN POLYURETHANE POLYMERS HANE POLYMERS

摘要

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 wherein Q is C2H2z+1, or (CH2)nN(R3)kT, T is a monovalent C1-C4 alkyl, amino-C1-C4-alkyl, mono-C1-C4-alkylamino-C1-C4-alkyl, or di-C1-C4-alkylamino-C1-C4-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 (I), 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 C1 to C4 alkyl; k = 0 or 1, being 1 if T is a monovalent group and 0 is T is a divalent group: R2 = H or C2H2z+1; R3 = C2H2z+1; R4 = H; R5 = H or CH3; n = 2 to 6; and z = 1 to 4. "n" is preferably 2 to 3 and z is preferably 1. Each R3 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 C2H2z+1.
