A process for alkylating a phosphorus-containing compound to provide an alkylated phosphorus-containing compound is provided which comprises alkylating 5 phosphorus-containing compound possessing at least one phosphorus-hydrogen alkylatable site with reactant which generates alkene and/or cycloalkene alkylating agent in situ in the presence of initiator, the alkylene and/or cycloalkylene alkylating agent alkylating the phosphorus-containing component to provide alkylated phosphorus-containing product. 

Process for the alkylation of phosphorus-containing compounds

A flame retarded thermoplastic polymer composition comprising a thermoplastic polymer and a mixture of metal salts of dialkylphosphinic and monoalkylphosphinic acid providing improved flame retardant performance and better processability compared to a similar composition containing only a salt of dialkylphosphinic acid.

Flame retardant compositions containing mixtures of disubstituted phosphinate salts and monosubstituted phoshinate salts

A flame retarded thermoplastic polymer composition comprising a thermoplastic polymer and a metal salt of phosphinic acid possessing a desired degree of volatility.

Phosphorus-containing flame retardant for thermoplastic polymers

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.

Process for preparing diaryl alkylphosphonates and oligomeric/polymeric derivatives thereof

Epoxy resins that are suitable for forming epoxy laminates that meet a UL-94 rating of V-0 comprise a hydroxy-terminated oligomeric phosphonate comprising the repeating structure &#x2014;OP(&#x2550;O)(R)OArylene-, where R is alkyl, as a flame retardant.
