Abstract:
A hydroxyphenyl or alkoxyphenyl phosphine oxide composition comprising (i) a first mixture of mono-(hydroxyphenyl) or (alkoxyphenyl) phosphine oxide isomers, (ii) a second mixture of bis-(hydroxyphenyl) or (alkoxyphenyl) phosphine oxide isomers, (iii) a third mixture of tris-(hydroxyphenyl) or (alkoxyphenyl) phosphine oxide isomers, and optionally iv) a minority amount of non-hydroxy or non-alkoxy tris-phenyl phosphine oxides is provided. Also provided are epoxy resins compositions with excellent flame retardancy and physical properties, which resins comprise the phosphine oxide composition.
