3,3'-oxy-bis([2,2'-di(bromomethyl)]) propanoic acid derivates, processes for their preparation and their use as flame retardant agents.

摘要

Novel derivaties of 3,3 min -Oxy-bis([2,2 min -di(bromomethyl)]propanoic acid} of formula (I) <CHEM> in which Y represents OR, chlorine or NH-R and wherein R represents hydrogen or an alkyl or aryl group, unsubstituted or substituted with 1 to 5 bromine atoms, are described. The novel derivatives of the invention have improved thermal properties and a high content of bromine, and are particularly suitable as flame-retardant agents. Methods of preparation of these novel compounds are described.
