The sequence of events leading to dihalide desorption and the role of vacancies will be described.
Poly(arylene ether)s (PAE) are generally synthesized via nucleophilic aromatic substitution of an activated dihalide with an aromatic bisphenol (2-7).
Similar conditions were used as described in the synthesis of poly(arylene ether methyl phosphine oxide sulfone) - the only exception being that 4,4[prime]-bis(fluorophenyl)phenylphosphine oxide (BFPPO) was used at the activated dihalide instead of methyl analog (BFPMPO).
Similar conditions were used as described in the synthesis of poly(arylene ether methyl phosphine oxide) homopolymer - the only exception being that 4,4[prime]-bis(fluorophenyl)phosphine oxide (BFPPO) was the activated dihalide instead of BFPMPO and 4,4[prime]bis(hydroxyphenyl)phenylphosphine oxide (BOHPPO) was used as the bisphenol.
Finally, zero frequency limit of [X.sub.s] is comparable with the static results of iron group dihalides in static fields where [mathematical expression not reproducible] increases rapidly with rising temperature and diverges at the critical and multicritical points [9, 20].

Nitration at ortho position to the ring's halo group(s), hereto referred as selective ortho-nitration, has been anything but selective and literature has no record of examples of adjacent dinitration of aryl dihalides. The mechanism of this reaction has been extensively investigated but is still the subject of animated discussion.

9, formulated as ln.sup.I, sub.[sub In.sub3 L In'II2C'9 1, but in any case it is clear none of these diamagnetic "dihalides" involve In-In bonded species.
