Simple two-component zero-halogen flame retardant

摘要

A flame-retardant additive is provided comprising a source of phosphorus and a polymer or oligomer which is a phosphorus/nitrogen-containing oligomer or polymer. These additives are found to be particularly suitable for use in polymer materials when used in combination with a second and different source of phosphorus, resulting in an additive having reduced smoke generation, reduced evolution of corrosive gases and improved flame-retarding properties.
