ABSTRACT:
Flame retardant compositions such as polyurethane foams are produced by incorporating an amino condensation composition. The amino condensation compositions are produced by heating urea or heating urea with other nitrogen containing compounds that will condensate with or react with isocyanic acid and/or cyanic acid or heating urea first then reacting the condensation compounds with other nitrogen containing compounds. The amino condensation compounds may be mixed with or reacted with carbonization auxiliaries, aldehydes and fillers to produce an amino condensation composition which is incorporated in more flammable organic compositions such as polyurethanes, polyester resins, epoxy resins, vinyl resins and other resins. The amino condensation salts of phosphorus, boron or sulfur containing compounds and the amino condensation-aldehyde resins may also be used as the flame retardant compound in this invention. For example, polyurethane foams can be rendered less flammable with the amino condensation compounds or compositions and utilized as insulating materials.
