摘要: Various phosphorus polymers and oligomers, particularly phosphates phosphonates, are commercially used as flame retardants. Some, such phosphate oligomers with hydroxyl groups, incorporated into polyurethanes, or paper textile finishes. Certain phosphonate phosphinate structures thermoplastic polyesters, fibers, for retardancy. Thermoset resins epoxy circuit boards rendered retardant by incorporation of ester the polymer structure. Flame-retardant cotton finishes utilizing phosphonium reagents to produce cross-linked phosphine oxide networks produced. Red is a polymeric form in Europe Far East flame-retardant additive. An oligomeric ammonium polyphosphate component intumescent systems, especially coatings fire barrier materials. Some phosphites antioxidant components. Oligomers phosphonic phosphinic groups scale inhibition. Vinylphosphonic acid have found specialized uses coating photolithographic plates. Phosphorylated acrylic monomers been useful improving adhesion dental repair materials. Ion-exchange show promise removal water pollutants. cellulose has medical use binding calcium gastrointestinal tract. starches rheological applications food products.
