Process for preparing diaryl alkylphosphonates and oligomeric/polymeric derivatives thereof |
| abstract |
A process is provided for the production of diaryl alkyl phosphonate by the reaction of triaryl phosphate with dialkyl alkyl phosphonate in the presence of alkali metal iodide catalyst; and, optionally, the diaryl alkyl phosphonate is reacted in situ with aromatic diol and, optionally, with at least one branching monomer, in the absence of other or further added catalyst to provide oligomeric and/or polymeric phosphonate products. |
