Abstract
PURPOSE: To obtain titled rigid foam suitable as a construction material, etc., by using a specified amount of a polyalkylene glycol containing ethylene oxide and propylene oxide, a catalyst containing an alkali metal, etc., and of an aromatic polyisocyanate, etc.
CONSTITUTION: Titled rigid foam is obtained by using (a) polyalkylene glycol having ≥30% hydroxyl group content and ≥300 hydroxyl number, containing 20W 50mol% ethylene oxide and 50W80mol% propylene oxide, (b) at least 0.05pt.wt., based on 100pts.wt. of component c, of a catalyst compound containing an alkali (earth) metal such as sodium hydroxide, potassium acetate, magnesium hydroxide or calcium benzoate, and (c) 3W15 equivalent weights, based on the total having a active hydrogen atms, of an aromatic polyisocyanate such as toluylene 2,4-diisocyanate or diphenylmethane-4,4-diisocyanate.
