Deoxybenzoin-based Anti-flammable Polyphosphonate and Poly(arylate-phosphonate) Copolymer Compounds
Synthetic polymers are used extensively as plastics, rubbers, foams, textiles, and construction materials; however, the flammability of many polymers is recognized as a safety hazard and an important challenge in polymer research. To reduce polymer flammability, halogenated small molecule flame-retardant additives are commonly incorporated into polymer materials. However, such halogenated additives may compromise polymer properties, and moreover pose environmental problems associated with additive leaching. To overcome these problems, researchers at UMass Amherst have developed halogen-free, inherently flame-retardant polymers. This invention provides deoxybenzoin-based anti-flammable polyphosphonate and poly(acylate-phophonate copolymer compounds with low heat release capacity values and high char yields.
