Poly metaphosphate

Finally, it is interesting to note that the value of a for the poly-(metaphosphate) chain [Strauss and Wineman (241 )] has the same order of magnitude as those of non-electrolyte chains with substituents of comparable size. Under the observed theta-solvent conditions (0.415 M aqueous NaBr), the screened long range electrostatic interactions are just balanced by the various other contributions to the excluded volume effect, but there is no reason to expect a simultaneous obliteration of short-range electrostatic effects1. 

Water-insoluble PEC were prepared by mixing oppositely charged polyelectrolytes, e.g. DEAE dextran with CMD [340,341], sodium dextran sulfate, poly(styrene sulfonate) (NaSS) [342], poly(sodium L-glutamate) (PSLG), poly(vinyl alcohol)sulfate [343], or potassium metaphosphate (MPK) [240]. They are useful as membranes or in biomedical applications [343,344].

Poly(phosphoric acid) is the high-molar-mass condensation product of orthophosphoric acid. The corresponding salts are called polyphosphates. The oligomeric, cyclic metaphosphate compounds, as they are called, are often also classified as polyphosphates.
