Application Of Organophosphorus Polymers

Organophosphorus polymers can be used to increase the flame resistance of fibers, synthetic resins and plastics, such as polyvinylphosphonates. Unsaturated phosphoric acid ester polymers, such as diallyl alkyl (or aryl) phosphonates and their copolymers, have the properties of transparency and wear resistance, and are suitable for making special optical glass, aviation glass, transparent sheet plastics, etc. . After cross-linked polystyrene and cross-linked polymethyl ketene undergo phosphination reaction, the synthesized phosphonic acid resin (structural formula) can be used as an ion exchange resin to remove high-valent metals (such as ferric iron) or Separation and purification of transition metals. Organophosphorus polymers and copolymers can also be used as coatings, paints, adhesives, internal plasticizers, films and fibers.
