Abstract:
Novel flexible and semi-flexible polyurethane foams having good hardness properties and superior resistance to permanent set are disclosed. The novel foams are produced by reacting an organic polyisocyanate with a polyether polyol and employing as a cross-linker an effective amount of a polymethylene polyphenylamine having a functionality of from about 2. 2 to about 2. 7 having a specific isomeric distribution. The cross-linker is easy to handle and is compatible with urethane foam systems.
