Abstract
PURPOSE: To obtain the titled polyurethane slab foam useful as bedding, etc., having high elasticity and high hardness, by using a specific amount of an adduct of a polyhydric phenol polyglycidyl ether with dialkanolamine as a crosslinking agent.
CONSTITUTION: 100pts.wt. raw material polyol (preferably a polyether polyol containing three hydroxyl groups, having an average molecular weight of 4,800W 6,500, and a primary ratio of 70W85) is reacted with preferably 1W10pts.wt. adduct of a polyhydric phenol polyglycidyl ether (e.g., catechol) with a dialkanolamine (preferably diethanolamine or diisopropanolamine or their mixture), a reaction catalyst, any other crosslinking agent, a blowing agent, and an auxiliary in necessary amounts respectively, or it is added to the reaction of a polyol and an organic polyisocyanate (e.g., TDI), to give the desired polyurethane slab foam.
