Abstract
Polyether polyols are initiated with aminocyclohexanealkylamines such as isophoronediamine and 1,8-diaminop-menthane. The polyols are useful in making rigid polyurethane foams, especially foams for pour-in-place applications, where they give a good combination of low k-factor and short demold times.
