ORGANIC PHOSPHORUS COMPOUND HAVING A PHOSPHATE-PHOSPHONATE BOND, AND FLAME RETARDANT POLYSTER FIBER AND FLAME RETARDANT POLYURETHANE RESIN COMPOSITION USING THE SAME

摘要

THE PRESENT INVENTION PROVIDES A PHOSPHATE-PHOSPHONATE COMPOUND WHICH HAS A LOW VOLATILITY AND A HIGH PHOSPHORUS CONTENT,DOES NOT EXERT ADVERSE INFLUENCES ON THE PHYSICAL PROPERTIES OF A PRODUCT CONTAINING THE PHOSPHATE-PHOSPHATE COMPOUND AS A MATERIAL, AND IS RECYCLABLE AND CAUSES SUBSTANTIALLY NO ENVIRONMENTAL LOAD SINCE A HALOGEN ATOM SUCH AS A CHLORINE ATOM OR A BROMINE ATOM IS NOT INCLUDED.A PHOSPHORUS COMPOUND CONTAINING A PHOSPHATE-PHOSPHONATE BOND IN ONE MOLECULE AND HAVING A SPECIFIC STRUCTURE HAS A HIGH FLAME RETARDING PROPERTY.BY USING A PHOSPHATE-PHOSPHONATE COMPOUND AS A FLAME RETARDING AGENT FOR A POLYURETHANE OR FOR A POLYESTER, PREFERABLE PLASTICITY AND FLAME RETARDING PROPERTY ARE OBTAINED. SUCH A FLAME RETARDANT AGENT EXERTS SUBSTANTIALLY NO ADVERSE INFLUENCES ON THE PHYSICAL PROPERTIES OF A POLYURETHANE FOAM OR A POLYESTER FIBER.
