FLAME RETARDANT POLYMERS CONTAINING RENEWABLE CONTENT

摘要

A flame retardant polymer is prepared from renewable content. In an exemplary synthetic method, a bio-derived flame retardant polymer is prepared by a polycondensation reaction of a biobased diol (e.g., isosorbide) and a phosphorus-containing monomer (e.g., phenylphosphonic dichloride). The biobased diol may be obtained either directly from, or through modification of, a biological product. Preferably, at least 50% of the mass of the biobased diol is obtained directly from a biological product. The phosphorus-containing monomer may be a phosphonic dichloride, dichlorophosphate, alkyl/aryl phosphonate, or other phosphorus-containing monomer known for flame retardancy.
