POLYOL MIXTURES CONTAINING A 1,3-AND/OR 1,4-BIS(AMINOMETHYL) CYCLOHEXANE-INITIATED POLYOL AND AT LEAST ONE OF A METHYLENE BIS (CYCLOHEXYLAMINE)-INITIATED POLYOL AND A CYCLOHEXANEDIAMINE-INIT IATED POLYOL, AND POLYURETHANES MADE THEREFROM.

摘要

Polyether polyols are initiated 1,3- and/or l,4-bis(aminomethyl)cyclohexane) and with either or both of a methylene bis(cyclohexylamine) compound and a cyclohexanediamine compound. 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.
