Abstract
New compounds, represented by the formulae I and II, ##STR1## wherein R.sub.1, R.sub.2, and R.sub.3, are independently C.sub.3 or C.sub.4, substituted or unsubstituted alkylene groups, are useful for catalyzing the reaction between an organic polyisocyanate and a compound containing a reactive hydrogen to form polyurethanes.
Claims15
A compound having a chemical formula I or II, ##STR10## wherein each of R.sub.1, R.sub.2, and R.sub.3 is independently a C.sub.3 or C.sub.4 substituted or unsubstituted alkylene group[s], provided at least one of R.sub.2 and R.sub.3 is substituted when R.sub.2 and R.sub.3 are both C.sub.4 alkylene.
A method for preparing a polyurethane comprising reacting an organic polyisocyanate with a compound having a reactive hydrogen in the presence of a catalytically effective amount of a compound having chemical formula I or II:
- wherein each of R.sub.1, R.sub.2 and R.sub.3 is independently a C.sub.3 or C.sub.4 substituted or unsubstituted alkylene group.
A method for preparing a polyurethane foam comprising reacting an organic polyisocyanate with a polyol in the presence of water and a catalyst composition comprising a compound having chemical formula I or II:
- wherein each of R.sub.1, R.sub.2, and R.sub.3 is independently a C.sub.3 or C.sub.4 substituted or unsubstituted alkylene group.
