Abstract
Abstract Flame retardant compositions of this invention are produced by incorporating a partially index (LOI) hydrolyzed amino condensation composition in a more flammable organic material. The partially hydrolyzed amino condensation compounds 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 thereby producing an amino condensation compound which is then partially hydrolysis is done by reacting it with a limited amount of water. The partially hydrolyzed amino condensation compounds may be used alone or may be mixed with or reacted with carbonization auxiliaries, aldehydes and fillers to produce a partially hydrolyzed amino condensation composition which is incorporated in more flammable organic compositions such as polyurethanes, polyester resins, epoxy resins, vinyl resins and other resins. The partially hydrolyzed amino condensation salts of phosphorus, boron or sulfur containing compounds and the partially hydrolyzed 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 partially hydrolyzed amino condensation compounds or compositions and utilized as cushion and insulating materials.
