摘要: Resilient foams based on melamine resins are prepared by foaming an aqueous solution which contains a melamine/formaldehyde precondensate, an emulsifier, a volatile blowing agent and a curing agent and then curing the foam. In this process, from 0.2 to 4% by weight of an alkali metal, alkaline earth metal or aluminum salt of an organic, preferably polybasic acid, of a polyphosphoric acid or of a boron acid are added to the aqueous solution.
