ABSTRACT:
A foam made from the reaction of a multifunctional isocyanate and a catalytic amount of an isocyanate polymerizing catalyst and method for making such foam are disclosed in which the foam is modified by forming the foam in the presence of water and a softening agent selected from the group consisting of a chlorinated alkane, brominated alkane, alkyl ester of an alkanoic acid, alkylene oxide, aromatic hydrocarbon, acylnitrile, aliphatic ketone, aliphatic aldehyde, aliphatic ether, alicyclic ether, amide of an alkanoic acid, and mixtures thereof, wherein the foam is modified by the water and the softening agent in an amount effective to provide a gel time which exceeds the rise time of the foam. A method of filling wall cavities with the foam and composition for preparing the foam are also disclosed.
