SYNTHESIS AND APPLICATIAN OF PHOSPHORUS-CONTAINING POLYMERIC FLAME RETARDANTS

摘要

With economic development, people's awareness of environmental protection and security has been greatly improved.more concerned about the ecological environment and the value of life.Because of its low smoke and Low toxicity such as environment-friendly features, Halogen-free flame retardants are widely used.Compared with halogen flame retardants, phosphrus flame retardants produce less poisonous, corrosive gas, working both in condensed phase and gaseous phase, having a high efficiency flame retardants.Phosphorus-containing polymeric flame retardants can reach the the following conditions: flame retardant with high efficiency, good thermal stability, good compatibility with polymer, no adverse effect on the mechanical properties of polymer materials.Therefore, the phosphorus-containing polymeric flame retardants were prepared and show good property of flame retardants in PA and PBT.
