This invention relates to a process for producing compounds derived from 9,10-Dihydro-9-Oxa-10-Phosphaphenantrene-10-oxide (DOPO). In particular, the invention relates to producing DOPO-derived compounds by reacting DOPO with diol compounds in the presence of a catalyst. This invention also relates to DOPO derived composition containing a high melting point diastereomer. The DOPO derived compounds may be useful as flame-retardants. 

Process for the preparation of DOPO-derived compounds and compositions thereof

Described are a particular group of novel aromatic hydrocarbon telomers that, on bromination, result in the formation of novel flame retardants having a uniquely beneficial combination of properties. The resultant flame retardants and uses thereof are also described. The disclosure includes descriptions of methods for preparing both the aromatic hydrocarbon telomers and the brominated flame retardant polymers.

Brominated flame retardants and precursors therefor

This invention relates to novel and useful toluene and styrene derived telomer distributions, such distributions being desirable substrates for the preparation of brominated flame retardants.

Bromination of telomer mixtures derived from toluene and styrene

New branched or star-branched styrene polymeric, telomeric, and monomeric product distributions, their preparation, their use as raw materials for bromination to produce flame retardants, the flame retardants themselves, and their use as flame retardants in various polymeric substrates are described.
