Abstract
Methods for rapidly curing flexible polyether-derived foam in situ by adding to the foam forming composition an ammonia containing material having a decomposition temperature below the temperature of the highest reaction exotherm of the foam-forming composition and decomposing the ammonia containing material by exposure to the heat of the exotherm produced by reaction of the foam-forming components to release ammonia to cure the foam by contact therewith.
