摘要：
Polyether polyols initiated with ortho-cyclohexanediamines such as 1,2- diaminocyclohexane are used in rigid polyurethane foam formulations in conjunction with an aromatic amine-initiated polyol, a polyester polyol, or a polyol derived from a renewable resource. The polyol mixture 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.
