Flame Retardant Potential of Phosphorus Esters

摘要

Phosphorus ester units may be incorporated into polymeric structures in several ways. Difuctional alcohol or acid monomers may be modified to contain phosphorus units and utilized to produce poly(ester)s. Thus a phosphorus-containing entity may be introduced into the polymer as a pendent group. Suitably-substituted vinyl monomers may be used to generate polymers with phosphorus-containing side groups. Phosphorus ester functionality may be introduced into polymer mainchain by polyesterification using difunctional phosphorus reagents or by ring-opening polymerization of phospholanes. Materials produced by all these methods have the potential to serve as useful flame-retarding additives for polymeric materials.
