Abstract
The present invention relates to the use of nitrogenous compounds of formula (I) and/or corresponding quaternized and/or protonated compounds for production of polyurethanes, to compositions comprising said compounds and also to polyurethane systems, in particular polyurethane foams, obtained using said compounds.
Claims19
A polyurethane composition comprising a reaction product of a polyisocyanate, a polyol, and a nitrogenous compound,
- wherein the nitrogenous compound is formula (I)
- with
- R1 and R2 being the same or different and each independently being hydrogen or an organic moiety of 1 to 30 carbon atoms,
- with R3 being H or an organic moiety of 1 to 20 carbon atoms, which may be interrupted by one or more heteroatoms, wherein an amount of the nitrogenous compounds of formulae (I), is a mass fraction of 0.01 to 20.0 parts (pphp) based on 100 parts (pphp) of the polyol.
